+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.
