Heltec Mesh Node T114 Rev 2.0


Mesh Node T114 has been upgraded to V2.0 version with the following changes made

1.The circuit board was changed from 4 layers to 6 layers so the RF part and the crystal oscillator part can obtain a more complete ground.
2.The circuit was changed from lead-free to immersion gold process, which is more friendly to signal transmission.
3.The position of some components was adjusted.
4.The RF path was optimized according to the six-layer board structure.
5.The direction of the 2.4GHz Bluetooth antenna and IPEX LoRa antenna interface was changed to make them farther away.
6.The data transmission can sent long data packets with meshtastic.

Notes


1. If you choose the T114 without a screen, you need to connect the device to a computer and view the status and logs through the serial port. Or with the Meshtastic App.


2. How to use?

There are two pins, USER and RST that bootloader will check upon reset/power:


●Double Click RST within 500 ms will enter DFU with Uf2 and CDC support (only works with nRF52840)



●USER = LoW and RST the device : Enter bootloader with OTA, to upgrade with a mobile application such as Nordic nrfConnect/Toolbox
