Updated DC brushed motor controller intended as an add-on for Teensy 3.x. TI’s CSD13383F4 FemtoFets replace the SOT-23 PMV31XN MOSFETS and Comchip’s CDSQR4148-HF high-speed switching diodes replace the SOD-323 1N4148 diodes of the previous board. The new components are super small, and I made the traces wider and attempted to provide a good thermal sink for the 12 V, 2.9 A FETs. The board can be used standalone in a breadboard or, better, attached directly to a Teensy 3.x to use the PWM output at pins 3, 4, 22, 23.

Sharp 1.17-inch, 38 x 184 pixel TFT-LCD display as an add-on to Teensy 3.1. Display requires no more than 130 microamps so it can be powered via digitalWrite(HIGH) from any Teensy GPIO pin. This display can be mounted on a breadboard or, soldered or with female headers, mounted directly onto a Teensy 3.x providing a very compact, low-power, high-resolution display either on top or bottom of the Teensy.

Simple DC brushed motor driver using TI’s DRV8837 1.8 A PWM-controlled H-Bridges. Board is designed to be mounted onto a Teensy 3.X although it can also be used on a breadboard. The H-bridges allow the motors to be driven both forward and reverse, with braking and coasting options as well. SLEEP pin HIGH enables the motors.

Test board for Sharp Memory LCD 128 x 128 pixel, 130 microAmp display.

Test board for very small 4 kHz piezo sounder.
