EME103B L/S-Band LNA PCB

Is a PCB for a circuit which can measure the voltage induced by moving magnets.

This version has rounded corners and has moved its LED holes to opposite sides of the board. They are labeled Crosser and Auto-Pilot

4 channel rotary encoder interface

Adapts the 10-pin 50 mil connectors with reversed pinouts on the Atmel ICE to standard 50 mil and 100mil 10-pin headers and provides a standard 100mil 6-pin AVR ISP header, a reset button, and test loops for Gnd, Vtg, and the spare pins on the AVR and SAM headers.

DO NOT USE ATMEL 50-MIL RIBBON CABLES WITH THIS ADAPTER! Use standard straight-through ribbon cables instead.

Two strips of thin double-stick tape above and below the ICE connectors will help keep the board secure.

USB Condom v1.0.
A little something for the tinfoil hat crowd ;-)
Full project details with BOM on GitHub.

Adapter for FTDI RS-232 cables to bring the pinout down to GND, TXD, & RXD. There are two variants: (A) with TXD in the center; (B) with RXD in the center. Pin 1 is always GND. Bonus Debug header and optional pull-up resistors (0402).

Use male 0.1" headers for the FTDI & DBG connectors, and female 0.1" headers for the A & B connectors.
