Product Description Summary Mesh Node T114 is a Low Power Consumption development board based on nRF52840 and SX1262, supports LoRa and Bluetooth 5.0 . which integrated various power interfaces (5V USB, lithium battery and solar panel) optional 1.14 inch TFT display and GPS module as accessories, and has powerful long-distance communication capabilities, scalability, and low power design. With Heltec nRF52 development environment and libraries. you can use it for LoRa/LoRaWAN development work, and also use it to run some open source projects, such as Meshtastic. Mesh Node T114 has been upgraded to ReV2.0 version with the following changes made : The circuit board was changed from 4 layers to 6 layers so that both the RF part and the crystal oscillator part can obtain a more complete ground. The circuit was changed from lead-free to immersion gold process, which is more friendly to signal transmission. The position of some components was adjusted. The RF path was optimized according to the six-layer board structure. The direction of the 2.4GHz Bluetooth antenna and IPEX LoRa antenna interface was changed to make them farther away. The data transmission can sent long data packets on meshtastic. Low Power Characteristcs Main Features MCU nRF52840 (Bluetooth), LoRa chipset SX1262.
