Bescor MP101 Libre

Notes on using the Bescor MP101 motorized pan head hardware with libre software.

No proprietary applications, SDKs, or similar are used.

Development Setup

The development setup is using a LattePanda 3. It is an Intel based board with an Arduino Leonardo built on board.

This should be similar to using other Arduino devices plugged into USB ports.

Pins

Pins on the MP-101 cable. Starting at "7PM", just after the key, going clockwise:

Use	Color	Pin	ArduinoPin
---	-----	---	--------
Speed	Yellow	1	? PWM
Left	White	2	D0
Down	Brown	3	D1
5V	Green	4	5V, second from left.
Up	Blue	5	D2
Right	Black	6	D3
GND	Red	7	GND under ICSP

The "ArduinoPin" column is how the Arduino pins on the Panda are labelled.

Wire Harness

I made a quick and dirty wire harness that works. My MP101 kit came with two extension cables. I used one of those to use the male headed to plug into the MP101, and the newly cut wires to connect to pins to plug into the Panda Arduino. I had short jumper wires with pin headers on each end. For the Panda male/male wire with headers is needed. If the board being used has pins not headers, a male/female wire jumper will be needed. In lieu of connecting the pins to the wires via soldering, WAGO crimpers were used. They work great and easy++.

Status

Early alpha. It moves in four directions, but doesn't stop or have regular controls yet. Just mapped out the pins to Arduino software.
