Several sellers in China have listed these HWfly-shaped chips powered by RP2040 for around $10. I asked one of the sellers and got confirmed that, for Erista and Mariko Switch, the flex cable to solder on the Tegra SoC is identical to the old HWfly flex cable.
I just ordered one to upgrade my old HWfly chip for my Mariko Switch, hope it will work.
"Compatible with Switch/OLED/Lite"
Update: I purchased it from a Chinese version of eBay, it only support Chinese and does not have international shipping, so I couldn't share a link. International buyers may have to wait until the manufacturer opens a global store on platforms like Aliexpress.
Update 2: Got mine and successfully installed. Everything from flex cable to cut position on the aluminum shield is completely identical to HWfly chip, I just disconnect the old HWfly chip from flex cable then connect the Picofly chip, and it instantly take me to Atmosphere.
I forgot to take a photo before installing the aluminum shield, but it looks very much the same as HWfly modchip.
