TTGO T-Echo SoftRF NRF52840 LoRa Module with 1.54 E-Paper display and BLE goo VDDIO interface voltage range: 1LILYGO T Echo is a version evolved from LILYGO T BEAM. 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 with Thread and Zigbee multiprotocol SoC. The LORA function continues T BEAM's LILYGO SX1262 (alternate for SX1276) version functional module. T SX1262 wireless transceiver module, using
