Bison Science is preparing to launch a project that aims to be a perfect solution to the Wi-Fi range limitations of existing boards, called the ESP32-M1 Reach Out Development Board.
The ESP32-M1 Reach Out development board is said to increase range up to two to three times, and is quoted to be more than 1.2km. The ESP32-M1 Reach Out is an excellent solution for developers, makers, engineers, and hobbyists who seek to develop robust communication systems using Wi-Fi and Bluetooth protocols even at a distance. It is integrated with an ESP32 RF SoC that makes getting going with long-range RF as simple as can be. The chipset features both a microcontroller and RF stage in a single package and guarantees a range of more than 1.2km using Wi-Fi 802.11b.
Though with a small size, the ESP32-M1 Reach Out has a methodical design that features amongst others, 17 GPIOS, 3 different voltage outputs, digital external interfaces, external antenna connectors, and a high-power radio front-end for Wi-Fi.
Features & Specifications of the ESP32-M1 Reach Out Development Board include:
- SoC: ESP32-D0WDQ6 RF clocked up to the frequency of 240MHz
