The ESP32-M1 Reach Out Campaign is Now Live

Now Funding: ESP32-M1 Reach Out

The ESP32-M1 Reach Out relies on Qorvo’s QPF4219 module to anchor its RFFE section and RFSW8009TR7 to switch between Wi-Fi and Bluetooth and switches TX/RX for Wi-Fi.

ESP32-M1 Reach Out is a high-power Wi-Fi development board that combines the ESP32 module with long-range Wi-Fi communication. While most other high-power Wi-Fi dev boards max out at 20 dBm transmit power, the ESP32-M1 Reach Out is able to transmit at 30 dBm (1 W) conducted, all while drawing power from the USB 3.0 port on your laptop or power bank.

The RFFE section of ESP32-M1 relies on Qorvo’s QPF4219 module and has a 33 dB transmitter gain and a 15 dB receiver gain at the module level. (The board itself is capable of transmitting from 21 to 30 dBm, though its output power can be adjusted through the ESP32 module at the firmware level.) After input and output matching, the on-board QPF4219 LNA receiver gain is 12 dB. At the input of the ESP32 chip, the receiver sensitivity is 8 dB higher. The bandpass filters, RF switches, and matchings are part of these measurements. Part of the RFFE is to select between Wi-Fi and Bluetooth protocol, and for Wi-Fi protocol to able to switch between TX and RX events for QPF4219 PA and LNA, Qorvo’s RF Switch RFSW8009TR7 were used for both functions.
