ESP8266 Takeapart - Collin’s Lab Notes #adafruit #collinslabnotes #adafruit

many electronics boards with wireless capability like wi-fi or bluetooth come with these silver modules so what secrets are hidden behind this shiny armor to remove it i'll try melting the board's solder with a hot air gun if we want to get in there even faster we can always get a little more direct heat from our friend mini hot plate once the board fully heats up we can gently remove the tin being careful not to disturb the components underneath inside we find the esp8266 itself a timing crystal and an spi flash chip to store the board's program you can see where the tin was soldered to the ground plane making it act like a faraday cage blocking outside radio frequencies you can also see there's one gap in the cage perimeter this is where the antenna trace went outside to talk to the world
