X, GND, and 5V need to be manually connected to their relevant pin location (if you want to use them). They are there simply so that I do not have to remember the pin location for those two things. I would connect them and now I would know their location. X would be whatever single pin you are trying to test.

This is meant to be used with a logic level translator and a FPGA to get various video outputs from PPUs. It may have other uses.

RC Senior Telemaster motor mount version 2. LEDs and resistors are 0805. Select resistors based on input voltage, LED voltage drop and desired LED current. I need the motor mount to span two inches for the AXI 4120 motor. I am using three V2 boards and one V1 board (attaches to motor) along with 9/16" Aluminum spacers. Will source the input voltage from the main 5S battery balance connector (21V). I am going to use yellow LEDs to match the yellow airplane covering. (P/N 150080YS75000) I am going to use 1K 0805 resistors 1/2W for the current limiting resistors.

TARS board for sep mech

Prototype

The board is for use in a short Ground Plane (GP) antenna for Amateur Radio Direction Finding (ARDF), with a single loading coil and matching circuit at its center feedpoint. It is designed to operate between 3.5 MHz and 3.6 MHz with an SWR below 1.5:1. Simply suspend the far end of the antenna six meters above the ground, plug the other into an 80m ARDF transmitter, and fox setup is complete.

The board is for use in a short vertical dipole (SVD) antenna for Amateur Radio Direction Finding (ARDF), with a simple matching circuit at its center feedpoint. It is designed to operate between 3.5 MHz and 3.6 MHz while providing a 50-ohm resistive load with an SWR below 1.5:1. The coax feedline runs up the center of the bottom antenna element and is shielded by it. The result is a “rope antenna” about 6.1 meters (20 feet) in length. Simply suspend the far end of the antenna six meters above the ground, plug the other end into an 80m transmitter, and the fox setup is complete.

A snap-off wire end insulator is included as part of the board design.

Breakout board for DWM1000 UWB module designed for nRF52 Feather.

The MCP4728 is an I2C quad channel 12-bit DAC with non-volatile storage, and a synchronous load pin for cases where channels need to be changed concurrently. This part is useful for applications where an analog trim value needs to be stored and loaded without firmware intervention.
