Heltec Mesh Node T114 Rev 2.0
Mesh Node T114 has been upgraded to ReV2.0 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 on meshtastic.
