Picowriter

Description

Picowriter is a battery powered eink typewriter. Similar to a Freewrite or Alphasmart, the Picowriter is intended for writing. Unlike these devices, the Picowriter does not have an integrated keyboard. Rather, you bring your own USB or Bluetooth keyboard for use with the Picowriter. Check the Wiki for more info.
