With the PCB on their way and expected to arrive next week, it was time to order the components required for the assembly. Here is a table with the references used, quantity and unit price (for ONE display).

TOTAL56,25€

A total of 40 € of components (excluding the power supply), for 1 display, so 80€ in my case as I want to try daisy chaining both displays together. A bit pricey for a prototype but some components will be re-usable, such as the drivers (mounted on sockets), and cable assemblies.
