CANFDuino supports CANFD, the latest version of the CAN bus standard, which can accommodate speeds up to 5 Mbps. It has two local ports with DB9 connectors in a housing that can be mounted on your vehicle or installed in your own projects. The platform is designed for tinkerers, hackers, and industry professionals looking for a ready-made, open source CAN bus solution that requires little or no hardware assembly.
Bllimpduino 2 is a very low cost open source autonomous airship. It consists of Arduino M0 airship controller board and on-board WIFI and laser sensors. Two vector differential thrusters and one lift thruster. The design is simple, yet exciting.
Plant Bot is an open source project based on ESP32 that allows a single PCB to perform the functions of detecting humidity, watering, providing lighting, and controlling and communicating with the user via WiFi/BLE.
USB-Cereal is a powerful, fully open source development tool that simplifies testing, development, debugging and manufacturing of devices using USB-C. Using the extended capabilities of USB-C, this unique hardware saves time and effort by simplifying debugging and factory log capture, as well as firmware update procedures.
Reflow-Controller is designed to control different types of reflow ovens, hot plates, etc. It's based on the ESP32-S2, so it can be programmed to work with WiFi applications, but it also has an onboard OLED display and three buttons for use as a standalone solution.
The cost of the board should be less than 50RMB, and it provides a lot of information, which is very suitable for novices to use as a development board to learn Linux.
This board and associated firmware can be used to switch between two serial NMEA GPS feeds based on repair status. The resulting feed is transmitted over a third serial line with RS232 levels. This board is designed around the Cypress PSoC CY8C27143. The PCB is designed using KiCAD.
Portenta X8 is a powerful industrial-grade SOM with a pre-installed Linux operating system onboard and can run device-independent software thanks to its modular container architecture. Securely perform OS/application OTA updates with onboard Wi-Fi/Bluetooth® Low Energy connectivity. It is basically two industrial products combined into one, with a power of no less than 9 cores. Utilize the Arduino environment to perform real-time tasks, while Linux handles high-performance processing. Portenta X8 features NXP® i.MX 8M Mini Cortex®-A53 quad-core up to 1.8GHz per core + 1x Cortex®-M4 up to 400MHz, and STMicroelectronics STM32H747 dual-core Cortex®-M7 up to 480Mhz +M4 32-bit Arm® MCU, up to 240MHz.
In early 2005, NEC Electronics launched small-pin-count microcontrollers such as PIC/AVR based on the 78K0S architecture. The 78K architecture has a register set similar to the i8085 and additional bit manipulation instructions. It is said to be a classic architecture, but the memory organization is simpler than PIC/AVR. There are various devices with dedicated peripherals, and the 78K series occupies a considerable share of industrial equipment. In the early days, only OTP/Mask products were available, so they were not popular among electronic crafts. However, the small pin count 78K series with flash memory is getting some attention from Japanese microcontroller geeks. Powerful IDEs (compilers, assemblers, simulators, etc.) are also provided for free. I built a very simple 78K0S flash programming adapter for these devices. Additionally, I built a universal programming adapter for V850ES, LPCxxxx, STM32F, etc.
This design mainly explains the circuit and software design of the node equipment, coordinator equipment and gateway equipment in the greenhouse, completes the front-end and back-end interaction between the web page and the WeChat applet, and completes the data transmission test and communication distance test.
All 12 I/O pins of this design are broken out to 0.1" headers. All 4 TX/RX channels and the reference clock are broken out to SMA connections.
This design is a breakout board for SGMII Gigabit Ethernet PHY DP83867C. It connects to SERDES via a SYZYGY-TXR connector to test and evaluate Ethernet over 1.25Gbps serial channels. 2 channels are used and CDR is required on the RX path. Compared to RGMII, SGMII significantly reduces the number of signals required for routing.
Connect to a 5" LCD paired with a Sipeed Tang Nano. This is an 800x480 LCD with RGB888 connections. All 8 bits of each channel are connected via SYZYGY connectors.
SYZYGY is an FPGA extension standard for medium to high speed interfaces. This design is a splitter for 4x PMOD connectors. All 32 I/O signals from the SYZYGY connector are brought out. 8 on each PMOD.
The design is a custom 3d model from Sensirion. Sensirion provides a 3d model, but it has very few features.
This design is a connector for the Raspberry Pi HQ camera.
The style of enameled wire is as usual, and the craftsmanship is still excellent. The power board designed this time is made of double panels, and a copper-laying design is applied. The insulation layer is laid first and then the copper. If the device on the front needs to be grounded, break the insulation layer and solder it to the copper.
The board of this design is intended to sit between the fundamental and harmonic boards and monitor the SPI data running to the display. Onboard ECP5 will mirror the display and output a copy to a digital monitor.
This design has a PMOD for the SD card to emulate the SD card to the host system.
A PMOD with a quad 7-segment display connected to a pair of 74hc595 shift registers. There are 3 tactile buttons.
