Description
Key Features
- Supports USB → 2-channel UART, or USB → 1-channel UART + 1-channel I2C + 1-channel SPI, or USB → 1-channel UART + 1-channel JTAG
- 2-channel high-speed UART up to 9 Mbps, hardware flow control CTS and RTS
- 1-channel I2C — convenient control of EEPROMs from PC or programming of I2C devices (OLEDs, sensors, etc.)
- 1-channel SPI with 2 chip select (CS) signals — simultaneous control of two SPI devices
- 1-channel JTAG — compatible with OpenOCD for debugging and testing (functionality recommended for self-verification)
- Built-in 3.3V / 5V level shifting circuit — switchable via DIP switch on the board
- Built-in self-recovering fuse and ESD protection — protection against overcurrent and overvoltage
- Aluminum alloy casing with a matte finish, CNC processed — durable and long-lasting
- High-quality USB-B and DC connectors with reverse connection protection
