ESP32-M1 Reach Out Development Board

Integrated with an ESP32 RF SoC, ESP32-M1 Reach Out is a compact 1W (30dBm) Wi-Fi radio ESP32-M1 development board that can achieve long-range communication of more than 1.2.km via Wi-Fi 802.11b. Powered by Qorvo technology, this board is designed to develop robust communication systems using Wi-Fi and Bluetooth protocols.

The small form factor ESP32-M1 Reach Out development board has a patch antenna structure and measures 40x60 mm. It features 15 GPIOs along with two accessible input-only IOs and also includes a CP2102 USB Serial Bridge (USB to UART Converter) along with digital external interfaces and external antenna connectors.

The board with its long-range capabilities can be used in remote monitoring and sensing, drone radios, long-range video streaming, and security purposes. It is based on the ESP32-D0WDQ6 RF SoC with a frequency of 240MHz and comes with 32Mbit flash memory. The board is powered with USB +5V and approximately more than 750mA when using high-power Wi-Fi front-end operation. The design features 3 different voltage outputs of +3.3V, +4.85V, and USB Voltage.
