At the beginning of the design, more consideration was to adapt to Meshtastic and SotfRF, so Bluetooth and low power consumption were considered when designing, and NRF52840 Advanced Bluetooth 5 was selected Thread and Zigbee multiprotocol SoC.

The LORA function continues T-BEAM's LILYGO SX1262 version functional module.

T-SX1262 wireless transceiver module, using Semtech SX1262 LORA RF transceiver chip design, working in the 868/915MHz ISM frequency band, integrated high stability TCXO 32MHz crystal oscillator, half-duplex transceiver module, power up to +22dBm, receiving sensitivity -139dBm.

Automatic transceiver Switching, internal transmission and reception channel isolation, advanced LORA spread spectrum communication technology, strong anti-interference and privacy, can realize long-distance wireless data transmission and reception.
