Overview
Pcba is an open-source printed circuit board by AllenNeuralDynamics, from the AllenNeuralDynamics/mis-focus-controller repository on GitHub. It is a 4-layer board of 80 × 60 mm with 30 parts on 68 nets, routed with 280 tracks and 48 vias.
Its parts include 6 connectors and 4 ICs. It belongs with the RP2040 boards of this library.
README
README.mdmis-focus-controller
A device for controlling the focus on the camera modules of the Modular Insertion System.
(previously named mis-cafomoco)
This board uses a Raspberry Pi Pico as a USB-to-PWM interface for the 3x BD65496MUV motor drivers onboard. The boards are stackable so that a stack of two can be used to drive 6 focus motors with one USB connection. This device was designed to be used with the 12V micro-metal gearmotors from Pololu, with the magnetic encoder add-ons for closed-loop control.
Usage
Below is a list of serial commands supported by the device. Most commands can refer to several motors at once with unique arguments. Motor lists are separated by commas; argument lists are separated by commas.
| Command | Example | Description |
|---|---|---|
is_busy\r\n | is_busy\r\n | Returns True\r\n if any motor is moving. returns False\r\n when the device is not busy; |
SET_SPEED <motor_0>,<motor_1> <m0_percent>,<m1_percent>\r\n | SET_SPEED 3,2,4 50,50,60\r\n | Set the speed of motors 3, 2, and 4 to 50%, 50%, and 60% repsectively. |
TIME_MOVE <motor_0>,<motor_1> <clockwise>,<clockwise> <ms>,<ms>\r\n | TIME_MOVE 0,1 1,1 3000,3000\r\n | Rotate selected cameras (0 and 1) clockwise (if 1, otherwise ccw) for specified time (in milliseconds). |
See the mis-focus-controller-sw for a pip-installable python driver.

Questions
How big is the Pcba PCB?
It measures 80 × 60 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Pcba use?
30 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pcba KiCad files?
From the AllenNeuralDynamics/mis-focus-controller repository on GitHub, at the commit this page was made from: the board is hardware/pcb/pcba.kicad_pcb and its schematic hardware/pcb/pcba.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcba design in my own project?
Its repository states no licence, so its author keeps all rights: ask AllenNeuralDynamics before reusing the design.
