This is a port of an earlier project to use the Fanstel PA-LNA BT832X nRF52832. See the earlier project for the what and why of ESP-LINK: https://www.openhardware.io/view/443/nRF52832-ESP-LINK-Shield-for-ESP8266-Wemos-D1-Mini

I also added some enhancements: 2 LEDs and a separate reset button for the nRF52832. In addition, you can now read serial debug output over the 10-pin IDC connector using a handy adapter: https://www.openhardware.io/view/484/IDC-10-pin-ARM-debug-adapter The nRF52832 is also powered from its own dedicated 300ma LDO, so that it doesn't compete with the the Wemos D1 Mini for current.
