+
+## Board
+
+The board comes with all components soldered from [JLCPCB](https://jlcpcb.com), when you bought with SMT Assembly Services. You need only
+solder the relays (3x units), KREs (3x 3 vias, 1x 2 vias) and a ESP12 (E or F). Its super easy.

+-   Small size: 70mm x 49mm
+-   Manual reset and flash buttons
+-   Flash friendly (as describe in FAQ)
+-   3 relays (because it is a cold component -- you can use inside your wall conduit box).

 ### How to firmware?
 
-Use [ESP8266-RTOS IDF Like](https://docs.espressif.com/projects/esp8266-rtos-sdk/en/release-v3.3/index.html#)
+This firmware was built in [ESP8266-RTOS IDF Like](https://docs.espressif.com/projects/esp8266-rtos-sdk/en/release-v3.3/index.html#).
+
+You can use a ESP8266 Programmer (and avoid to solder serial headers) or via serial (TX, RX, GND).
+
+If you have a FTDI / CP2104 or CH340 with DTR and CTS, the board is flash friendly (auto enter in programmer mode and restart after flash).
