Raspberry Pi’s New Microcontroller Update: A Retro Hardware Lover’s Dream!
The Raspberry Pi team updates the RP2350 microcontroller, fixing bugs and delighting retro hardware enthusiasts with a GPIO tweak. This A4 stepping removes the need for extra circuitry, supports self-decrypting binaries, and offers high resistance to side-channel attacks. GPIO is now 5 V-tolerant, making retro computing projects cleaner and simpler.

Hot Take:
Hold onto your resistors, folks! Raspberry Pi’s RP2350 update is here to make retro hardware enthusiasts’ dreams come true. Forget about those extra bits and bobs, as the new A4 stepping is the drop-in replacement we never knew we desperately needed. It’s like trading in your old jalopy for a Tesla, but without the eye-watering price tag. So, grab your soldering iron and let the GPIO magic commence!
Key Points:
- RP2350 microcontroller gets a shiny A4 update with bug fixes and GPIO delights.
- No more messy circuitry; A4 is a drop-in replacement for the old A2.
- New SDK requirement: Version 2.1 is your new best friend.
- Raspberry Pi challenges hackers to test the new security hardening.
- GPIO now 5 V-tolerant, perfect for retro computing fun!
