Just finished building and testing my newest V16 cart reader pcb and can confirm that the new SA1 sram write code works perfectly. I've also designed a new SD module pcb that uses the same schematics and components as the microSD module but has a full-size sd slot.
Just finished building and testing my newest V16 cart reader pcb and can confirm that the new SA1 sram write code works perfectly.
The difference is that with V15 there was a little pcb on the Arduino Mega that did the 5V/3V supply switching and with V16 all that was integrated back into the cart reader shield pcb, which is more cost effective. The 5V/3V switch and the On/OFF switch are separate again because it's cheaper that way since you only need to order one kind of switch for the whole cart reader.Functionally all the different cart reader versions are the same. So the new SA1 Sram writing code will work with all versions as long as you have installed the Adafruit Clock Generator.
