PCB to enable the RP2040 Zero to be interfaced with various PLL evaluation boards
Page under construction!!
The 1st batch of prototype boards is en-route from JLCPCB. Testing to commence soon!
The PCB marshals SPI etc from the RP2040 Zero and is designed to plug directly onto several PLL evaluation board headers
Supports channel switching, Morse Key input , external GPS engine, optional true EEPROM for the RP2040
Supports several varieties of ADF4351 Evaluation board (including SV1AFN), MAX2870 and MAX2575 boards
Offers plugin support for some ADF5535 boards (Firmware not yet available)
Pads are provided for optional supply line decoupling, 3.3V rail segregation diode, lock detect indication (where presented) and an onboard 3.3V regulator if needed.
Additional optional components are 0805 size or bigger for ease of construction
-Documentation Setup instructions 1st Draft
NOTE This is a work in progress. Component values etc. may change after evaluation of performance!.
