- It arrives at your doorstep ready to use
OR
- Get assembled boards using the files in this repository
- Solder header of your choice
- (Except for RP2040 version, or if ordering Pico from JLC) Solder RPi Pico - use Pico-W if you want DaynaPORT capabilities for a Mac
- Go to https://github.com/ZuluSCSI/ZuluSCSI-firmware and grab the Pico/Pico_DaynaPORT version of the latest release and flash to the board by connecting via USB while holding BOOTSEL (or toggling the boot dip switch for RP2040)

PDN redesigned on Hybrid V1.0 boards to provide better ground return paths. V1.0b implements the change and is the first publicly available variant in this repository.
-
v1.0b Hybrid and v1.0 RP2040 boards have the wrong pad deleted for keying pin on 2.5" header - should be 17 instead of 21.
Patch: Do not install/cut pin 17.
Change: Connector rekeyed.
