@macdaddy posted: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.
| Signal Name | ESP8266 Pin | CC1101E Radio Pin | Dupont Wire Color |
| VCC | 3V | VCC | Yellow |
| GND | G | GND | Green |
| MOSI | D7 | MOSI | Blue |
| MISO | D6 | MISO | Violet |
| Select | D8 | CSN | Brown |
| SCLK | D5 | SCK | Orange |
| GDO2 | D2 | GDO2 | Red |
| GDO0 | D1 | GDO0 | Gray |
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.
