By using particular IO scanning detection, the 5 IO Keypad takes only 5 IOs to control all of the onboard push buttons and joystick. 10 push buttons, 1 joystick (five positions), 5-bit interface.
Features: PL2303TA onboard (the latest device, compatible with PL2303HXA). Supports windows XP/7/8/8.1/10/... 3 power mode : 5V output, 3.3V output, or powered by target board (3.3V-5V). 3 LEDs: TXD LED, RXD LED, POWER LED.
The Waveshare CAN Board SN65HVD230 features an accessory onboard CAN transceiver, which is pinout compatible with PCA82C250. It is powered from 3.3 V and features ESD protection. The SN65HVD230 CAN Board is ideal to connect microcontrollers to the CAN network. Designed for operation in especially-harsh environments, it features cross-wire protection, loss-of-ground and overvoltage protection, overtemperature protection, as well as wide common-mode range.
Features: Original FT232RL onboard. Supports Mac, Linux, Android, WinCE, Windows 7/8/8.1/10... 3 power mode : 5V output, 3.3V output, or powered by target board (3.3V-5V). 3 LEDs: TXD LED, RXD LED, POWER LED.
Ultra-narrow bezel, conpact size, with onboard voltage translator. Adopts 4-wire SPI and I2C interfaces, better compatibility, fast data rate. Comes with online development resources (examples for Raspberry Pi/Arduino/STM32).
