Vernon I now have all the parts to complete one of these RTC Adapters. I have purchased the same boards as you have. I see the wire connections on the ESP8266 board via your picture however you don't show in your pictures the connection to the CC1101E radio board. Could you provide a picture of the wired connections to the radio board. I have a friend printing the cases and Mark sent me the latest RTC file to flash the board.



Thank you in advance!

Mark's website is the BEST resource- so use it. https://www.silogic.com/trains/RTCAdapter.html

He has pictures for BOTH 10 pin and 8 pin radio versions

The boards have labeled silkscreen pin names beside the pins.

This is a good quick and easy test bed that does not require soldering or wirewrap. These Dupont wires are not that great of a connection and since they are just push on, they can fall off. Find a more secure way to interconnect these devices for the longer term.

FWIW: These wires were first made by Berg Electronics which was sold to DuPont and is now owned by Amphenol. Pins are 0.025 x 0.025 inches square.

Here are two videos demonstrating the Adapter. The first is a brief tour of my trainroom showing the hardware and the second shows the RTCAdapter in action.

On my RTCAdapter web page, I have two more videos which show the installing of Python and the uploading of the RTCAdapter compiled binary file into the ESP8266.
