Breakout/adapter board for the ADIS16407 10 DOF IMU

Reference design for the EM7180 sensor hub and MPU9250 9 DoF motion sensor and BMP280 pressure sensor. SENtral manages the sensors providing quaternions, Euler angles, linear acceleration, gravity and drift-compensated altitude at 400 Hz update rates. Master I2C bus and SENtral GPIOs broken out for addition of external sensors.

Description

This is the main board for a small computer based off the popular ATMega328P, the heart of the Arduino Uno. There are two processors on board, one acting as a graphics processor using the TVOut library, and the other as the main processor, with 6 input lines for a controller of some kind.

Changes

Rev 1.2:

• Changed to rounded board
• Moved silkscreens and a couple traces around for nicer placement

Rev 1.1:

• Initial Revision

v0.2 of the A7105 shield (fixes transposed SPI pins)

This item is a battery holder/coin cell adapter PCB that lets you mount a standard CR2032 battery holder over top of a PCB layout that uses a soldered-in battery. It basically converts the pin layout from one of many odd 2- pin and 3-pin board styles into the common battery holder style. In the future, battery replacement will be a snap! Save your gear from leakage, damaged traces and lost sounds! Was designed for Yamaha DX7 synth. The Instructions are here.

Quad analog vector generator

Second iteration of robot mainbaord for RoboRuckus game.

This is a small board that uses MAX3453E chip to add a USB interface for an FPGA board. This extension is designed to fit into an extension connector on Numato Mimas V2 FPGA board, but it probably could be used with other boards that use 6x2 connectors.

The source code is available on GitHub.

The board is untested.

Inline 6 channel buffer for arcade VGA upscaler - Designed for MAGfest

This is the smallest board I can cram all the splitter parts and traces into..

This is a splitter for a WS2812B bitstream where one leg of the stream is delayed by a user-selectable number of LEDs. The delay is determined by closing solder jumpers such that the sum of closed jumpers equals the delay. Each unit of delay selected on the jumpers skips that number of input pulses times 24 before enabling the Dd pin output to copy the Di pin. The Do pin always outputs whatever is received on the Di pin.

This requires a Silego SLG46120V CMIC (like a mini FPGA) programmed as described in Application Note #(TBD). The GreenPAK designer project is also available on github at (TBD).

NOTE: The input pins are rearranged some compared to previous boards. This necessitates a different programming jig and modifications to the pin assignments in the GreenPAK Designer project.
