• Description: Development Boards & Kits - PIC / DSPIC MICRO-101 KIT
• Manufacturer: Gravitech

Specifications of MICRO-101

• Rohs: yes
• Product: Development Platforms
• Tool Is For Evaluation Of: PICAXE
• Core: PIC
• Interface Type: USB
• Operating Supply Voltage: 5 V

Please refer to PICAXE datasheet for pinout.
Four servo output terminals are
connected directly to output pin 4-7 as
labeled on the board. Use a jumper to
select the power provided to servo
sockets. The default position is VCC
(+5V). You may wish to move this
jumper to VIN position to provide extra
power to the servos.
power the servos, always check to
make sure the voltage supplied does
not exceed the specifications of the
particular brand of servos you are
using.
The Micro-101 board has Triple input
power. The board can be power by
I/O:

OUT0-OUT7: Output pins directly
from the PICAXE microcontroller.
OUT0 and OUT1 connected to LEDs
for testing.
IN0-IN2 and IN6-IN7: Input pins
directly into the PICAXE
microcontroller.
RED: Power to the servos – can
be select by a jumper. It is usually
a red color wire on the servos.
BLK: Ground to the servos – it is
usually a black color wire on the
servos.

USB, using 9V battery or 2.1 mm wall
power adapter. It is recommended to
keep input voltage under +14VDC when
using a wall power adapter. You may use
either center-positive or center-negative
wall adapter. The board will
automatically convert them into the
correct polarity. Power ON LED comes
on when external power is used, and the
ON/OFF switch is ON.
On board 5V regular circuit can draw up
to 500mA. This is enough for most of the
experiments. However, please use
external power supply when drawing
more than 500mA.
Reset switch is for resetting the PICAXE.
The red/green user-programmable LED
can be activated by placing the jumper
on LEDs header. LEDs turn ON by
writing a LOW to output 0 for green and
output 1 for red. Writing both LOW
simultaneously will show, at a distance,
as amber.

GND: is a common ground for
every pin. This pin must be
connected to ground when using
external power supply on the
target board.
VIN: is an actual input voltage.
VCC: is a regulated +5VDC. It
can be draw up to 500mA.
3V3: is connected to the internal
regulator and can source a
maximum of 50mA. You may use
this pin to power your 3.3V circuit.
