Dual-band RF Manager V1.2

Introduction: A dual-band portable radio frequency housekeeper made using ESP-12F and Hummingbird wireless modules that can copy, save, edit, and transmit 433 and 315 remote control signals. This version is physically verified.

2022.08.11 The firmware author Guo Ren has open sourced the firmware (2.8.4) code. If you need it, you can get it from https://github.com/bug508/RF. If you need the latest version of the firmware, please join the firmware author Q group: 1131935621
 
2022.06.12 Many friends sent private messages asking for the shell 3D model file of the front and rear shells split into two files. I have split and packaged all the shell models of versions 1.2 and 1.3 and uploaded them to the attachments of the project. If you need to go to the last attachment to download
 
2022.06 .06 RF Manager V1.3 has been released. If you are interested, you can check it out. . https://oshwhub.com/ys-tao/shuang-pin-ye-pin-guan-jia-v1-3
Update content of version 1.3:
1. Added CH340C chip and automatic download circuit. This version can directly use the U port Burn firmware. PCB diagrams of two interfaces, Micro (5pin) and Type-c (16pin), are provided.
2. The Type-C version adds a charging indicator light, which lights up when charging and goes off when fully charged. Micro's board has been laid out long ago, so I'm too lazy to add it. If necessary, open the pcb with an editor and add it yourself.
3. Optimized the thickness of the shell, reducing it from the previous 20mm to 16.5mm. A wire antenna slot is added inside the front panel of the casing, which can embed an antenna (for actual measurement results, please refer to the antenna test in the next article); a groove is designed inside the back cover, which can accommodate an NFC card.
4. Non-professionals can simply test the effects of several antennas. You can refer to it.
5. When welding the board, I took a few photos of the welding process and provided them with simple instructions. Veterans please ignore them. Novices can refer to them. .
 
 
Statement:
1. The original intention of this project is to merge multiple 433/315 radio frequency remote controls into one to facilitate the management of multiple remote control scenarios for electric doors, gates, and garage doors. This project can only be used when you have the original remote control. If you have the right to use it, the original remote control signal will be copied and saved. Functions such as blind scanning and credential stuffing are not provided. Please use it legally.
2. This project is an open source project. You can make it as you like, and you can also drive it for your convenience. However, it is only for spare parts and cannot be used for commercial sale of finished products.
 
Origin: The initial inspiration for this project came from the radio frequency housekeeper box of the workshop director that was uploaded on Douyin. Unfortunately, the author did not publish the production tutorial and firmware files. If you want to reproduce one, you can only design and make it yourself. In order to make the RF butler, I also studied the RCSwitch library sample files. However, I am a complete novice in programming. After studying for a long time, I can only read and transmit signal codes. I have never figured out how to store and customize signal names on the web page in AP mode. I understand. Fortunately, when I was studying and collecting various information, I found Xiaohan Electronic Technology, the owner of UP, at Station B. He has single-frequency firmware in his QQ group. After designing the circuit, you can directly flash it in and use it. In addition to only supporting Except for the single frequency, everything else is perfect. Unfortunately, the author may be busy with studies or have other research projects. The firmware that supports dual-band has only been released as a beta version in a hurry. The user experience is not very satisfactory. Fortunately again, the leader in the group, Nutrat, rewrote a new set of dual-band firmware and shared it. After several updates, the firmware is now perfect. . Special thanks to everyone mentioned above.
 
Introduction:
1. This project uses ESP-12F as the main control, Hummingbird Far-R1 and Far-T2L as the radio frequency signal receiving and transmitting modules, and a 4-pin 0.96-inch OLED module as the display system. Because most of them use off-the-shelf modules, the PCB circuit board circuit is very simple and almost only provides the peripheral circuits and battery charge and discharge management of the ESP-12F.
2. This radio frequency manager can copy almost all 433/315 frequency fixed code remote controls on the market.
2. I am only responsible for designing the PCB board and shell. The firmware file is written by Nut Mouse. If you need the firmware, please add the firmware author QQ group: 1131935621.
 
 
Simple instructions for use:
1. The design was originally designed to simplify the circuit and reduce costs. This version V1 .2 There is no U-port programming chip and circuit designed, and a programmer is required for programming. The latest V1.3 version is designed for direct U-port burning. However, since the proofing board has not yet arrived, it is not possible to verify whether there are any errors. We will release direct U-port burning after the new board arrives and is verified to have no problems. recorded version.
2. The order of the programming ports on the PCB is according to the order of the ESP-01 dedicated programmer. You can solder the pin headers and insert them into the programmer. Remove the pin headers after programming. You can also use Lichuang. An open source project for burning clips (https://oshwhub.com/zhqsoft/shao-lu-jia-zi-pcb) modified the probe arrangement to create a dedicated burning clip. I changed it myself and will post it here after the items I bought arrive and are verified to be normal. 3. The remote R1 module is installed vertically. When soldering, you can first solder a single-core copper wire on the corresponding port of the PCB board (just peel the network cable), solder the back (cut it flat after soldering), stick out 2-3cm from the front, and then put The R1 pad is inserted into the corresponding copper wire, positioned and soldered, and finally the excess copper wire is trimmed off. 4. The remote T2L module can be directly attached to the board and soldered, or it can be supported and soldered with pin headers. 5. The PCB board size is 36*70, and both 0.96-inch and 1.3-inch 4-Pin OLED modules can be placed. However, you must pay attention to whether the order of the 4-pin screen on the board is consistent with that of the OLED module. Generally, the difference is the order of VCC and GND. , if it does not correspond to your OLED module, use an editor to open the pcb file, hide the copper layer, modify the logos and lines of VCC and GND at the screen connection on the board, then re-lay the copper and save it.
6. The designed shell size is 76*42*20. The shell 3D printing file is currently only drawn to fit the 0.96 screen. If you need 1.3, you can leave a message and wait for me to draw it and upload it when I have time.
7. Four M2*3*3.2 injection molded copper knurled embedded nuts need to be plugged into the reserved holes at the four corners of the front panel of the housing. Before plugging, you can drip glue into the reserved holes on the panel to connect the back cover and the front case. Requires 4 M2*10 flat head screws. There are many pre-embedded copper nuts and screws on a certain store for just over 1 yuan each with free shipping, and with the daily sign-in red envelope, 20 pieces with free shipping only cost a few cents.
8. If you use the case I provided, the PCB needs to be printed with a thickness of 1.2mm. The maximum battery size available is 603040. The capacity is generally 800mAh. Batteries no larger than this size can be put into the case.
 
Directions for subsequent improvements:
1. Since I have not thought of a simple light transmission solution and do not have fiber optic materials on hand, all the battery charging management indicators have been streamlined. In the future, the indicators may be added and used to lead to the casing with optical fibers.
2. For the screen 4pin interface sequence problem, the lead-out pad may be used to freely switch the VCC and GND sequences through flying wires or direct tin stacking, or a DIP switch may be used to switch.
3. The current programmer version and the U-port direct programming version are two independent versions. They may be changed to an integrated version in the future. The programming port, CH340 chip and circuit are all designed, and the programming chip and circuit parts are marked with silk screen checkmarks. Come out, you can choose to solder the entire on-board programming part according to your own needs, or choose not to solder the on-board programming and use an external programmer instead.
4. Complete the ADC port detection voltage circuit of the ESP-12F chip. If you remember to add battery power display to the firmware later, you can adapt it directly.
5. If you have better solutions for the above parts or other parts that can be optimized, please leave a message.
