The KAmod ESP32 POW+RS485 board equipped with the ESP32-WROOM32D 4MB (32Mb) module supports 2.4 GHz Wi-Fi, RS485 communication, also has a USB-UART converter, an efficient power supply system and a 40-pin connector compatible with Raspberry Pi, making it an ideal solution for home and industrial automation
The KAmod ESP32 POW+RS485 board contains the ESP32-WROOM32D 4MB (32Mb) module, which enables communication in a 2.4 GHz Wi-Fi wireless network. A USB-UART converter with a USB-C connector was used to program the ESP32. The module is connected to the RS485 interface - a popular solution in home and industrial automation, enabling communication via a 2-wire twisted pair, e.g. in the MODBUS standard. The board is complemented by an efficient power supply system, which operates at an input voltage of 8 to 32 V, and provides stabilized voltages of 5 V and 3.3 V with significant current efficiency. The design of the board corresponds to the SBC of the Raspberry Pi family - it has dimensions of 81x56 mm, and all important I/O ports and supply voltages have been led out on a characteristic 40-pin connector.
