Description

H21R2x is a ESP32-C3 Wi-Fi+BLE module based on the STM32G0 MCU and ESP32-C3-MINI-1-N4 d 2.4 GHz Wi-Fi and Bluetooth 5 module. It is a compact and versatile module that combines Wi-Fi and Bluetooth Low Energy (BLE) capabilities. It is based on the ESP32-C3 chip from Espressif Systems, which features a single-core 32-bit RISC-V CPU running at up to 160 MHz.

The module includes built-in Wi-Fi and BLE antennas, as well as support for various communication interfaces such as UART, I2C, SPI, and GPIO. It also features integrated power management and security features to ensure reliable and secure operation.

With its small form factor and low power consumption, the ESP32-C3 Hexabitz module is ideal for a wide range of IoT applications, including smart home devices, wearables, and industrial automation. Its modular design allows for easy integration with other Hexabitz modules to create custom solutions tailored to specific requirements.
