LILYGO T-RSC3 ESP32-C3 board features isolated RS232 & RS485 interfaces, 5 to 24V DC input

LILYGO T-RSC3 is a relatively compact ESP32-C3 board with WiFi 4 and Bluetooth LE 5.0 connectivity, support for RS232 and RS485 communication protocols through a DB9 connector and a terminal connector respectively, and a wide 5V to 24V DC power input. LILYGO had already made an ESP32 board with CAN Bus and RS485 interfaces called the T-CAN485, but without any isolation. The new T-RSC3 offers both RS232 and RS485 interfaces, but no CAN Bus, protected by isolated transceiver modules that should make it safer to use in industrial environments. LILYGO T-RSC3 board specifications: Wireless module – Espressif Systems ESP32-C3-MINI-1U module with ESP32-C3 RISC-V microcontroller @ 160 MHz with 400 KB SRAM, 2.4 GHz WiFi 4, Bluetooth 5.0 LE & Mesh, 4MB flash, and a u.FL antenna connector Industrial control interfaces RS232 via DB9 connector, RSM232MT5V isolated transceiver with 3000V isolation, 4.75~5.25V input, 5V/50mA output, baud rate from 1200 to 256,000 […]
