The ADuC-H7020 board is shipped in protective anti-static packaging. The board
must not be subject to high electrostatic potentials. General practice for working
with static sensitive devices should be applied when working with this board.
microcontroller without need of fancy soldering skils. This board is designed to fit
in normal DIL40 socket, so you can make your prototypes easy and troubles free.
ADuC7020 is unique with the 1Msps ADCs and DACs and with the 3 phase PWM.
