FTDI-be-gone v0.4

by nsayer.

2 layer board of 1.28x0.60 inches (32.41x15.27 mm).
Shared on February 27th, 2016 08:16.

This board will take a Cypress Semi CY7C65213 USB UART and a MAX3243ECRHBR RS-232 level converter. The Cypress Semi part uses USB class drivers built-in to the OS, so there’s no opportunity for vendor driver shenanigans like “FTDI-gate.”

POV Twirlie v0.2

by nsayer.

2 layer board of 6.00x0.50 inches (152.40x12.70 mm).

Uses the same firmware as the Tiny Blinky. Mount it on a dowel and twirl it between your hands and watch the lights trace out POV patterns.

This version moves the battery inwards slightly to try and improve the balance, and moves the LEDs closer together to make better patterns.

FE-5680A power / interface board v1.1

by nsayer.

2 layer board of 1.35x1.58 inches (34.29x40.00 mm).

Rubidium standard breakout/adapter. Connect a surplus laptop 18V-24V DC power supply and it outputs +15V and +5V for the FE-5680 (the +5 can be disabled by breaking a jumper if your unit doesn’t require +5). The PPS and serial I/O are presented on a SIP-4 and the RF output is on a separate 2 pin header.

This is a modification of the Pi Power circuit.
