NerO Module Datasheet

Version 1.0

Doc ument Reference N o.: FT _001285

C learance N o.: FT DI#4 85

Great in all circumstances where external power is used - especially for designs with higher power

requirements such as driving displays/LEDs/ Wi-Fi etc. An excellent solution for 9V battery powered

solutions, automotive (12V) and POE designs as well.

Note 3 - NerO is FCC/CE certified as is the original UNO, and so is suitable for commercial

applications as well as hobbyist/maker projects

4.1 Power Supply

The NerO board provides alternative power supply sources with an On/Off Switch (SW1):

2. 5V over the USB cable connected to the Micro-B USB CN1 port.

The 9V or 12V option is recommended in designs using the NerO to supply power to Arduino shields

Once the power supply is connected and turned on, a Green LED power indicator will be turned on. When

the DC supply is on, the 5V Buck regulator will also be turned on, its 5V power output will serve the

module including peripherals of Atmega328P MCU and 3.3V fixed LDO. The 3.3V LDO will provide power

to the FT231X USB to UART bridge device.
