Did you get your day off and get around to making one, or are you still waiting for the parts and the programmer?

Once you've got yours made, it's "I've shown you mine, you show me yours", then we'll start in the programming.

With the soldering, it doesn't have to be that good, it's only DC. A lot of the gear we work with is digital microwave radio, 4 gigs up to about 18. No room for less than perfect soldering there, a lumpy joint becomes an extra inductor or capacitor :problem: . After working with those for the last 15 years your soldering looks pretty good...

Hi @lbcomms, just wondering if these are suitable for this project? Or will I have to live with my embarrassing soldering skills.

It'll be OK for development and testing, but too big and fragile (the wire connections) for a final fix inside a radio, especially a mobile. Lots of connections to come loose, fall off, or become noisy.

Some of those dev boards also use a regulator with 12V max input, feed them with 13.8V+ from a car alternator or a base power supply and an expensive chain reaction (i.e. radios PLL chip) awaits...
