Desk of Ladyada – RP2040 Adalogger, C6 Feather, Floppy and some RS-232 #DeskOfLadyada #adafruit @adafruit

This week, we worked on some testers and a few small designs. First up is the RP2040 Adalogger Feather which worked first try, so we’re already on to the tester – using our classic RP2040 brains, we’re now able to get a tester going in under an hour.

Next, we’re circling back to our floppsy interface board: we wanted to stock some floppy drives but found that a bunch of the ones we ordered don’t have an index pulse, so we designed a little test sketch to let us know if we are able to read MFM sectors.

We’re also still testing the ESP32-C6 Feather. We love using a TFT FeatherWing because it lets us verify I2C and SPI functionality – we’re dilly-dallying a bit but hope to send these PCBs out in a week or two.

Finally, we designed an IR transceiver, updated HUSB238 Type C PD, and designed two RS232 level shifters!

And this week on The Great Search – Finding a pin-complete RS-232 transceiver
