PGA2040

by Pimoroni

Image of Board

A minimal RP2040 breakout board wrangled into a Pin Grid Array, with a maximal dash of retraux style. PGA2040 has no USB port, LED or buttons but it does have an embed-friendly 21mm square footprint, 8MB of flash and lots of exposed RP2040 pins to play with.

Features

  • Powered by RP2040
  • Dual ARM Cortex M0+ running at up to 133Mhz
  • 264kB of SRAM
  • 8MB of QSPI flash supporting XiP
  • Crystal oscillator
  • On-board 3V3 regulator (max regulator current output 300mA)
  • 48 pins, arranged with 2.54mm (0.1”) spacing in a Pin Grid Array
  • 30 multi-function General Purpose IO (4 can be used for ADC)
  • 8 GND pins
  • Input voltage range 3V - 5.5V (on VB pin)

About the RP2040

The RP2040 microcontroller is a dual core ARM Cortex M0+ running at up to 133Mhz. It bundles in 264kB of SRAM, 30 multifunction GPIO pins (including a four channel 12-bit ADC), a heap of standard peripherals (I2C, SPI, UART, PWM, clocks, etc), and USB support.

One very exciting feature of the RP2040 microcontroller are the programmable IOs which allow you to execute custom programs that can manipulate GPIO pins and transfer data between peripherals - they can offload tasks that require high data transfer rates or precise timing that traditionally would have required a lot of heavy lifting from the CPU.

CircuitPython 9.0.0-alpha.5

This is the latest development release of CircuitPython that will work with the PGA2040.

Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.

Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
