Wiblocks --- NB1A -- ATmega328 + DAC + RTC

NB1A Microcontroller Board

The NB1A is a physical computing development system that is compatible with the Arduino software environment. For system development a variety of peripheral modules are available. All of the ZB1 peripherals are compatible with the NB1A. The datasheet is located here

Features

Non-catastrophic Infelicities

There are two known fabrication mistakes on the NB1A Rev1 PCB. These are minor mistakes that affect the assembly of the board not the functionality. Perform these reworks prior to starting the assembly procedure documented in the datasheet.

NB1A Pricing

The NB1A PCB contains two minor mistakes that affect the assembly of the board. Please review these issues prior to ordering. PCBs cannot be returned for either of these two known issues.

Assembled boards are assembled to order and typically ship within one business day.
