The test board contains a number of interfaces and the power supply for the ATM18. It is used for experimentation and for easy connection of hardware enhancements, sensors, actuators and other "accessories". The size of the test boards is 80 mm x 50 mm, the mounting holes have a distance of 72 mm and 44 mm.
