Micro USB connector 2. Status and PWR LEDs moved to edge of PCB – and remain visible when a shield is placed on the expansion connectors. 3. On-Off Switch for added user convenience 4. FTDI FT231X USB UART bridge (Note 1) 5. 5V Switching regulator vs LDO regulator (Note 2) 6. FCC/CE certified ( Note 3) Note 1 - FT231X is one of the latest X-series family of USB UART solutions from FTDI. It has larger communication buffers at a lower cost compared to our popular ubiquitous FT232R device. FT231X has 3.3V output levels and 5V tolerant inputs . FTDI provide drivers for its USB bridge devices across many platforms including certified drivers for Windows, including Windows 10. Note 2 -The NerO Buck Switcher regulator is much more energy efficient than an LDO device especially at higher Voltage inputs. It can supply a full 1A current at 5V without breaking sweat, or anything else. Copyright © 2016 Future Technology Devices International Limited 5 NerO Module Datasheet Version 1.0 D oc 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): 1. 9V or 12V DC supply, 2.1mm power DC Jack Connector CN2. 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 SW1 – On/Off Switch Switch Mode ON DC × OFF Table 1 - Switch Mode USB × 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. Figure 2 - DC Power Supply Copyright © 2016 Future Technology Devices International Limited 6 NerO Module Datasheet Version 1.0 D oc ument Reference N o.: FT _001285 C learance N o.: FT DI#4 85 When a USB cable is inserted, the VBUS will supply the 5V to all the peripheral and 3.3V LDO . Figure 3 - USB Power Supply 4.2 Micro-controller The on-board Arduino controller is the Atmega328P 32-pin TQFP microcontroller from ATMEL’s 8-bit Microcontroller family. This microcontroller runs at 16MHZ from a 5V power supply. For further details of the Atmega328P Microcontroller, refer to the Atmega328P datasheet.
