Low component's boards soldering

Take now the Arduino, the SD card reader and the charging board : IMG_6387.JPG

Place the Arduino board like the image below. Don’t apply too much strength ! If you can’t insert the board check if there is some bended pins. IMG_6388.JPG

Next place the SD card reader and the charging board like this : IMG_6389.JPG

Make sure all the boards are flat on the PCB. IMG_6390.JPG

Solder just one pin of the Arduino board, check the placement and solder the opposite pin. IMG_6391.JPG IMG_6392.JPG

Solder the other pins. Be very careful ! Don’t forget some of them. forget.JPG

Same thing on the SD card reader and the charging board. Solder one pin, check placement and solder the other pins. IMG_6396.JPG IMG_6397.JPG
