About this part

The Heltec Mesh Node T114 V2 is a low-power LoRa board that pairs an nRF52840 with an SX1262 radio, made for Meshtastic and MeshCore mesh messaging. Its low sleep current and solar panel connector suit battery-powered nodes, and you can order it with a 1.14-inch TFT screen, an L76K GNSS module, both, or neither.

SX1262 LoRa, up to 21±1 dBm out, -135 dBm sensitivity at SF12, 125 kHz
Bluetooth 5 with Bluetooth mesh, 1M ROM and 256 KB SRAM
USB-C, battery, solar panel, IPEX LoRa antenna and GPS module connectors, plus two 13-pin headers
Runs from and charges a 3 to 4.2V lithium battery (not included)
About 11 µA in deep sleep and about 9 mA with GPS and screen off
Comes with a LoRa antenna, two battery connectors and two header strips

Pick the 863-928 MHz or 433-510 MHz version to match your other nodes and the band allowed where you use it.
