There’s a global shortage of STM32F405 chips used in the Kung Fu Flash and it’s currently very hard to get the chips. No one knows how long the shortage lasts but probably well into 2022.
Kung Fu Flash Cartridge for Commodore 64.
Professionally SMT assembled board. ENIG finish with Hard Gold Edge Connector rated up to 1000 reinserts. This is much more durable than HASL edge connector that will wear out fast.
I will ship the card without MicroUSB-connector as the USB feature is useless for most people. Leave a message on the ‘Order Notes’ textbox when you Checkout
if you want me to solder the MicroUSB-connector.
