Going to custom silicon removes the supply chain hardening benefit of compiling your own FPGA code from scratch, but it greatly reduces the barrier to entry: while Precursor costs about $600, the Dabao sells for about $9. To compensate for the lack of transparency into the physical construction of the chip, the Baochip-1x is packaged in a WLCSP with a polished back-side, facilitating IRIS-style inspection. You can’t check every wire and connection using IRIS, but it’s better than simply trusting that whatever is in a black plastic square contains exactly the chip you were promised, no more, no less.
