Blink Sense Move.

A general purpose PCB/Toolkit for easy usage of sensors and actuators

Hardware

1. maximum PCB dimensions: 100×100mm ( = 1,76/10pcs @jlcpcb )
2. uses teensy 3.2 as mcu
3. features

• 2 mosfets
• h-bridge
• amplfiers for external sensors
• display (only dotmatrix for now, v2 will also offer pins for oled)
• stepperdriver
• clean audio output with lpf
• potentiometers
• buttons
• patchable io

4. version 2 will feature

• midi
• choice of display
• possibly cleaner powersolution

MCU-Ideas

( supported by Arduino IDE )

1. ATmega328p (AVR, 20 MHz, 8-bit, @as_used_in(Arduino UNO)), pP 1.60€, Datasheet
2. NXP MK20DX256 (ARM Cortex-M4, 96 MHz, 32-bit, @as_used_in(Teensy 3.2) ), pP 9.00€, Datasheet
3. STM32F446RE (ARM Cortex-M4, 180 MHz, 32-bit, @as_used_in(Nucleo F446RE + Arduino for STM32)), pP 9.00€, Datasheet

Boards

1. Teensy LC (approx 13 Euro) | Teensy 3.2 (Pro: Fast, Audiocapabilitys. Contra: Not super cheap)
2. Arduino Nano (Pro: Compatibilty, cheap. Contra: CH340-Driver issue with cheap Variations)

Ideas for Features

1. Felix´ Audio Output board
2. 1 or 2 Mosfets with Diodes
3. 12v Input with good Quality Voltage converter
4. Stepper Motor Driver
5. H-Bridge
6. 7-Segment-Display
7. Add-On-Interface for stuff like Encoders or Analogsticks and similiar stuff.
8. motor board only ( H-bridge+mosfet, stepper-driver, PWM for high-current/loads )
9. Making the wiring Modular
10. Mic- and Piezoamp, maybe also a switchable direct out to Felix Audio out.
11. frequency devider / counter ic
12. Making it modular (plugging and using boards together, with one microcontroller)
13. encoder
14. 2 potis

Bill of materials

• 3.5 mm jack
