Kit for the new GPS Analog Clock Driver
A complete kit for the New GPS-Synchronised Analog Clock Driver including the VK2828 GPS module, PCB and all onboard parts - everything in the Parts List published in September 2022 plus some double-sided tape to hold down the GPS module.
This kit is for the AA-powered version; if you want to power it with larger cells, you will need to add your own cell holders, wiring and possibly a connector.
The photo shows the kit after assembly with two AA cells installed (not included).
Note: a limited number of the D1 Mini version of the kit are available. There is also a separate shop item without either module: SC6929.
Kits sold from now on use the v1.2 firmware that provides multiple pulse width options for sweep hand movements.
