New ESP32 development board DMtech DEV01 with NB-IoT interface

Post by danielm » Sun Jan 06, 2019 4:51 pm

Hi, I am developing new development board based on ESP32-WROVER.
Most interesting feature is onboard NB-IoT modem Quectel BC66 and cellular antenna.
It will probably be released as open source after successful tests.
Can be used on top of custom carrier board as some sort of control/communication module or the design can be used as starting point for development of use-case specific board which makes use of mass-produces modules (ESP32-WROVER, BC66) with great price.

Prototype of the board was assembled. Initial test shows that the board can attach to NB-IoT network and antenna sensitivity seems to be pretty good as well.
