Badger 2350 is an all-in-one badge wearable with a fast updating 2.7" electronic paper screen, built-in rechargeable battery and sturdy polycarbonate case. Hang it round your neck with the (included) Badger lanyard or prop it up on your desk - either way it's ready to go straight out of the box. It's way more than just a event badge too - the four-level greyscale screen would also be great for displaying charts, signage or QR codes.

Features

  • Display: 2.7" four-level greyscale electronic paper (264 x 176 pixels)
  • Powered by RP2350A (Dual Arm Cortex M33 running at 250MHz with 520KB of SRAM)
  • 16MB of QSPI flash supporting XiP
  • 8MB of PSRAM
  • Raspberry Pi RM2 module (CYW43439), supporting IEEE 802.11 b/g/n wireless LAN, and Bluetooth
  • 1000mAh LiPo battery:
    • MCP73831 charger with 455mA charging current (datasheet)
    • XB6096I2S battery protector (datasheet)
  • PCF85063A real-time clock for waking from sleep (datasheet)
  • Polycarbonate case with teal back
  • 4-zone mono LED case lighting
  • Buttons:
    • Five front user buttons
    • Reset (and sleep) button
    • Home (and boot) button
  • Connectors:
    • USB-C connector for charging and programming
    • I2C connector (Qwiic/STEMMA QT) for attaching breakouts
    • SWD debug connector
  • Comes fully-assembled (no soldering required)
  • Includes matching 2-clip lanyard
  • Dimensions with case: 84mm (W) x 76mm (H) x 20mm (D)

Note

There is no power switch. Since mainline CircuitPython does not support low-power modes for the RP2350 (i.e. sleep/deep-sleep), the LiPo will be drained fast when running with CircuitPython. So to make full use of this board you either have to hack the hardware and add a power-switch, or hack CircuitPython and implement the alarm-module for the RP2350.
