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
  1. version 2 will feature
  • midi
  • choice of display
  • possibly cleaner powersolution

Pre v01

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
  • AKL
  • 595 (SMD?)
  • IRF530 (SMD)
  • 7seg/4Digit
  • spannungsregler MC7805CD2TG (SMD) (1A 5V für teensy und externe komponenten)
