Smart swaps for hard-to-find cards
We can't wait until the chip shortage is over and dev boards are plentiful again, but instead of waiting for someone to fix the supply chain, we've put together a list of close substitutes and of potential replacements for your next project. Unhappy with pending orders for your favorite Raspberry Pi or Arduino? Use the infographic below to find an alternative - maybe this will be your new favorite thing!

Arduino Nano 33 BLE Sense – at Arduino
Arduino Nano RP2040 Connect — same form factor but RP2040 (Dual M0+) instead of nRF52840 (M4) Arduino Nano Every - same FF but 8-bit ATMega4809 vs. 32-bit nRF52840
BBC micro:bit V2 – at Adafruit
Adafruit CLUE - same FF, similar nRF, but 240px display instead of 5×5 LED ELECFREAKS Pico:ed V2 - same FF but 7×18 LED matrix based on RP2040 and larger/denser
PJRC Teensy 4.0 – On PJRC.com
PJRC Teensy 4.1 - bigger FF bit adds more Flash, mSD slot, Ethernet pins SparkFun MicroMod Teensy Processor - same chip in SFE's MicroMod ecosystem (requires MicroMod support) Arduino Portenta H7 Lite - sort of a different class, but also based on M7 if you really need that grunt (almost 4x the cost though)
Raspberry Pi 4, Model B* – at sparkfun
Rock Pi 4 Model C+ - 64-bit Rockchip RK3399 (dual-core Cortex-A72, quad-core Cortex-A53) in Pi FF Khadas VIM4 - Amlogic A311D2 64-bit (quad-core ...
