INTRODUCTION
ADuC-H7020
provide low cost way to develop with ADuC7020
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.

ELECTROSTATIC WARNING
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.
BOARD USE REQUIREMENTS
Cables:
Depends on the used programming/debugging tool. It could be 1.8
meter USB A-B cable to connect
ARM-JTAG-EW
to USB host on PC or LPT cable in
case of
ARM-JTAG
or other programming/debugging tools. You will need a serial
cable if not for programming, than for configuring the board.
Hardware:
Programmer/Debugger – some of Olimex programmers are
applicable, for example
ARM-JTAG, ARM-JTAG-EW,
or other compatible
programming/debugging tool.
