This device uses triangle screws, but they are easily accessed, and the unit is easily opened otherwise. Points for serial flashing are on the back side of the board after opening the case. These points are clearly labeled for G, Vcc, Rx, Tx, and IO0. Soldering on temporary pigtail wires for the serial flash is highly recommended. The points are too far from the edge of the board to use probe type spring clips.
Some additional suggested console modifications to do after flashing and configuring the template are listed below
