#rp2040 — Public Fediverse posts

From the #DECtalk Mini github repository I commpiled with the #Pico-SDK today the RPi #RP2040 Pico version and changed it
from USB serial 115.200 Baud
to GPIO0/1-TTL-Serial 9600Baud.
Sounds fine on the left 3.5mm Audio channel
(GPIO28/Pin 24) of a
#Olimex RP2040-Pico-PC Board :)

I am slowly getting better at soldering, 4 out of 7 successful #MechanicalKeyboard PCBs now - all three of my diode-free #GraphTheory wired keyboard PCB designs have worked (eventually) ⌨️🎊

Finally calling this done! Say hello to the HellSplit a hand-wired, asymmetric 40% split #ortholinear keyboard with vertical column stagger and two rotary encoders. Powered by a pair of Raspberry Pi Pico's #RP2040 and #KMK firmware

I recently (a few weeks ago) finished putting the latest version of my Dactyl Lynx #keyboard together, using my Snowshoe MX single-switch PCBs, and I'm incredibly happy with the results!
