Pycom WiPY 3.0 Without Headers

Added to your shopping cart

A small, space conscious development board for the Pycom MicroPython enabled enterprise level system in package based on the ESP32 chipset featuring both WiFi and Bluetooth connectivity. The board features both a chip antenna and u.FL connector for longer wireless range in addition to an on board button and Tri-Color LED. This particular variation of the board does not come with headers, rather bare plated-thru-hole vias allowing the user to connect their own wires or breadboard standard spaced headers (0.1 inch). A perfect IoT development board for those looking to program in MicroPython.

The 3.0 variation features the following upgrades:

  • Deep sleep current draw fixed, now only 19.7µA
  • Upgraded RAM from 512KB to 4MB
  • Upgraded External FLASH from 4MB to 8MB
  • Antenna select pin moved from GPIO16 to GPIO21 (P12)
