Remote Control

Cable tester umbilical interface board.

ATTiny85 based DRV8871A Motor Driver/Remote Control board for Vortex I-II RV vent fans. See:

http://www.rv-project.com/projects/vortexremote.php

for project details (assembly instructions, BoM, Arduino Sketch, etc).

40 pin Dual In Line extension/header test PCB.

PROTOTYPE

This is Prototype Version P1.5: Some component values may change as the design is tweaked to perfection. So there is some risk that modifications will be required going forward. But if you feel adventuresome, then feel free to order this board and start building. But please plan on contacting the developer for help and updates.

The board is designed to mate with the ARDF 2-Band Mini Transmitter board, also available on OSH Park. Board outline is designed to fit Hammond waterproof enclosure manufacturer part #1554F2GYCL or #1554G2GYCL.

This allows for the testing of Sin/Cos and incremental encoders without the need for a servo drive.

Raspberry Pi shield that has support for both SPI-driven DotStar LEDs and RGB Matrix. Barrel power supply, backflow current protection, and 5V signals to LEDs.

Contains power protection circuit that prevents under- or over-voltage to the Pi and LED strips, includes diode to prevent back powering the Pi from 5V LED connectors. Capacitors to smooth voltage and handle inrush current spikes.

Provides 2 sets of 5V, Clock, Signal, and Ground pins to drive DotStar LEDs. Clock and signal are connected to SPI0 and SPI1 registers for driving DotStar LEDs from hardware without software SPI. All signal pins for LED and RGB flow through ‎74AHCT245 chips to convert 3.3V to 5V signal voltage for better compatibility.

This also has a 4-channel ADC chip that uses I2C. This was added to support a project that uses a potentiometer to provide inputs.
