NanoHat Proto
From FriendlyELEC WiKi
1 Introduction
- NanoHat Proto is a expansion board which has the same dimension as that of a NanoPi NEO/Air and can be stacked on a NanoPi NEO/Air.
- It is like a breadboard and has 14 columns of 100 mil (2.54mm pitch) land. Users can place various parts such as chips, resistors, LEDs and etc on the board.
- It has an onboard 32K EEPROM chip AT24C32D whose address is 0x50. This EEPROM is available for data storage.
