The Haitronic Ttgo HS2343 board is based on the ESP32 dual-core microcontroller and includes a 1.54-inch LCD with capacitive touch. The BMA423 accelerometer supports step counting, activity recognition, and gesture recognition, while the PCF8563 serves as a real-time clock. It is powered via Micro USB and features a connector for a 3.7 V lithium battery.
It supports Wi-Fi 802.11 b/g/n and Bluetooth 4.2 BR/EDR and BLE. Programming is available via UART download or wirelessly through OTA, and SDK software development and the FreeRTOS operating system are supported.
