Electronic design
The concept design I made is simple : a 'Mother' board is link to 'child' board. So, the assembly let you organised them regarding to your needs...
'Mother' PCB are made for teensy 3.2 and LC (only !!!)
and integrate pin connection to add Wiz850io or Wiz820io for OSC protocol using RJ45 (ethernet cable).
Regulator pin connection are compatible with Pololu D36V6F5 & D24V5F5, or by using my PCB and LM7805. A minimum of 500mA and a heatsink is recommended. Just don't mess with the direction !
Teenzy 3.2 and LC are usbMidi compliant, which mean they can be used as a midi device... So, a good versatile choice for music and digital projects.
I've made several Version/Revision, Related to my needs. All of them have been used in my projects/instruments.
I'm not a PCB supplier and print PCB for my need but manufacturer made them by 10pcs. I'm not always used all of them... So, sometimes have some rest. I can sell all of them until they're done...
If you know exactly what I am talking about and have questions or just have a project and don't know where to start,... drop me a mail (florentcolautti[@]gmail.com)
Mother "MTST"
Teensy 3.2 / LC — ethernet or usbMidi (usbMidi can be used only if there's no regulator !)
Allow:
--> 5v regulator or not
--> 2 Stepper driver & 4 PWM
--> 2 motor driver & 4 PWM
--> 8 PWM & 4 digital In/Out
--> 8 PWM & 1 Servo & 3 digital In/Out
Mother "Rev3"
Teensy 3.2 / LC — ethernet or usbMidi
Closed to MTST, without regulator but with 2 In/Out (useful for 2 servo or 1 analog IN & 1 digital In/Out)
(If servo and usbMidi are used, pin connect have to be 90° angle)
Mother "Rev1" - populated
Teensy 3.2 — ethernet
--> 8 PWM or 8 digital In/Out and (or not) 5V regulator.
Regulator
Pcb regulator for LM780x, can be used verticaly or horizontally regarding the PCB used
"Motor board"
Provide 4x power voltage for drive 'devices' (i.e : LEDstrip, DC motor, solenoid,...)
Very simple circuits using 10k resistor, 1N4001/1N4004 diode and N-channel mosfet transistor (I personnally used RFP50N06 or RFP30N06 but any others TO-220 N-channel should work)
Note: the circuit is recommend to be used on voltage up to 24v <9Amp (peak)- <5Amp (current).
If you just drive Leds or small motors, heatsink are not need, but I will recommend for any other situation.
"1 motor"
Single "Motor Board"
"Audio-Board"
Pcb for signal processing (like audio synthesis) application using Teensy 3.2 (only! not compatible with Teensy 4...) and audio adapter using OSC protocol.
Note: By the add of the ethernet connection, a simple SPI change have to be write on the code. The reading of SD card for Sample reading is supposed to be compatible, but I never try.
"Audio-Board" with Regulator
Same with regulator
"3MS"
Integrated PCB that host teensy 3.2/LC, 3x A4988 Stepper driver, 3x digital In/Out (mostly for the 'Position Stop' button) and have output for Motor Driver : my Motor board or for High power motor driver like the bts7960 or the VNH5019
"assembled exemple"
Set with 4 Pwm, 2 stepper motor and a 5v Regulator, all powered by a unique Ac->Dc 12v power supply and pilot by Rj45 cable, using 0SC protocol
