Yufeng Nano remote control

Yufeng nano/mini micro remote control (Arduino nano/promini main control + mpu6050 + nrf24L01 + OLED), two high-precision joysticks, PCB size 10*7.5CM, can be used to do various interesting projects. It supports two modes: normal and debugging. In the debugging mode, the joystick can be fine-tuned to the center position and the control reverse direction (the open source version of the program currently does not have screen display content and debugging mode).

There are two types of NRF24L01 modules painted on the Nano version PCB. One is the patch type, which I used for testing. You can choose one of the pin type. When making, pay attention to soldering the Mpu6050 module last (only solder the solder pins on the PCB first), because the battery box is fixed with a screw under the 6050. Install the battery box first and then solder the 6050 after the power-on test is normal.

The information package contains some reference open source materials, including a sample file of the receiving board of the Arduino Promini master control, as well as a reference program, on which you can freely play.

The excess finished products are sold on Xianyu. If you need them, you can contact me.

Materials:

​100uf aluminum electrolytic capacitor*2;
10, 104 ceramic chip capacitor 0.1uf*1;
11, AMS1117-3.3 step-down chip*1;
12, 6*6*6 key switch*4;

3. Other accessories materials:
1. A number of pin headers and female headers for welding;
2. Jumper caps*2 (There is a switching pin above the rocker, which is used to switch the rocker button function or Bluetooth function, and is reserved for the future. Used to upgrade the Bluetooth connection function, if not available, you can also short-circuit it directly);
3. Some M3 screws and nuts;

4. Power supply materials (supports 18650 and 14500 battery boxes, 14500 battery is recommended, and can be installed with a 3D printed bottom plate):
1. 18650 battery/14500 battery*2;
2. 2 series 18650/14500 battery box*1;
3. 18650/14500 battery charger*1;
