BeagleBoard.org BeaglePlay is an easy to use, affordable open source
hardware single board computer based on the Texas Instruments AM625
SoC that allows you to create connected devices that work even at long
distances using IEEE 802.15.4g LR-WPAN and IEEE 802.3cg 10Base-T1L.
Expansion is provided over open standards based mikroBUS, Grove and
QWIIC headers among other interfaces.
This board family can be identified by the 24c32 eeprom:
