ESP32-S3 LoRa development board

The MCDODO T-BeamSUPREME combines an ESP32-S3FN8 dual-core LX7 microprocessor with a SX1262 LoRa transceiver operating at 915MHz. It includes a GPS module using either a U-blox MAX-M10S-00B or L76K chip and a 1.3inch SH1106 OLED display. The board ships with Meshtastic firmware pre-installed for immediate mesh networking use.

Makers building Meshtastic nodes

This board suits developers and hobbyists who want a ready-to-use Meshtastic platform with integrated GPS and display for location-aware messaging. It is not for buyers who need a board without a screen, those requiring a different LoRa frequency band, or projects that demand a lower-power MCU without wireless connectivity.

1.3inch OLED and 915MHz LoRa headroom

The 1.3inch SH1106 OLED provides clear status and map data at a glance while the SX1262 transceiver handles long-range 915MHz packet radio. The ESP32-S3FN8 core manages Wi-Fi and Bluetooth duties alongside mesh routing. Headroom decreases when driving the display continuously or logging high-rate GPS tracks, which increases current draw and reduces battery life in portable deployments.

Questions sur cet article

Does the ESP32-S3FN8 dual-core LX7 need any external components to start running Meshtastic?

The board integrates the SX1262 LoRa radio, L76K GPS module, 1.3 inch SH1106 OLED and Wi-Fi/Bluetooth on the ESP32-S3FN8, so only a USB-C power source is required to begin.

Can I keep using my existing 915 MHz LoRa sensors with the SX1262 radio on this board?

Yes, the SX1262 operates at 915 MHz and is compatible with other 915 MHz LoRa devices when they share the same spreading factor, bandwidth and coding rate settings.

How do I confirm the L76K GPS is acquiring a fix after power-up?

The 1.3 inch SH1106 OLED displays live satellite count and position data once the L76K GPS module locks, providing immediate visual confirmation.
