I sent an order to the factory for TinyFPGA B2 boards a few weeks back and they have finally arrived. I've tested three of the boards and they appear to be in good working order. However, I have quite a few more to test and I have been putting off making a test rig for it. So today I'm working on a simple pogo-pin test and program rig that will load the USB bootloader bitstream onto the SPI flash and test the clock, voltage regulators, and all IO pins on the board.
And I'm off to KiCad to design my pogo-pin test rig!
