Moduł uniwersalny mikrokontrolera Cortex-M3 NXP LPC1768FBD100, leżak magazynowy.

Na płytce piny procesora wyprowadzone na złącza oraz listwy pinowe, złącze miniUSB, gniazdko Ethernetowe i kontroler ATHEROS AR8030.

Sądzę ze może służyć jako płytka developerska.

Po podłączeniu do laptopa przez kabel USB zapalają się diody na płytce a następnie część gaśnie.
Na laptopie płytka jest widoczna jako urządzenie USB w następujący sposób:
