QT Py

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
  • QT Py (SAMD based)
  • QT Py (RP2040 based)

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?
