Two Versions of the QT Py
- AdaFruit and Seeed Studio have SAMD21 and RP2040 versions of the QT Py (XIAO on Seeed Studio) with the same form factor
- QTPy49 Breakout card
RP2040 vs SAM version
- RP2040 is faster (125 MHz vs 48 MHz)
- RP2040 has 2 cores vs 1
- RP2040 has more Flash
- RP2040 has more SRAM
- The RP2040 version is more expensive, but about the same cost if the SAM version is used with an external Flash
- SAMD21/RP2040 Arduino Boards – Which 32-bit Microcontrollers should you use?
QTPy49 Breakout Card
