3 Power and Connection
Power is supplied for the N51 EVB only through a 5V DC adapter or external power cables. The N51
EVK provides one M5X0-PWR cable and one Micro-USB cable for data communication.
3.1 Power Supply
N51 EVB supports different types of power supply:
⚫5V/2A DC adapter
Insert the DC output end into the DC port of the EVB.
⚫Soldering external power cable
3.1.1 5V/2A Adapter
Figure 3-1 shows the recommended power adapter for N51 EVB.
Figure 3-1 Power adapter
3.1.2 Soldering Power Cable
The N51 EVB provides solder pads for external power cables, as shown in Figure 3-2. The input voltage
ranges from 3.4V to 4.2V and a 3.8V regulated power source is recommended.

Figure 3-2 Soldering pads
The power source supplies voltage to the module directly in this manner. Do NOT connect the pads reversely.
Otherwise, the module will be burned and cannot be repaired.
3.2 Communication Connection
3.2.1 M5X0-PWR Board
M5X0-PWR board is developed on PL2303 chipset by Neoway and used to convert USB to UART. You
can also choose another USB-to-UART cable/board based on FT2232, CP210X, and other chipsets.
M5X0-PWR is connected to the N51 EVB through 4-pin cables, which have been soldered to the power
board in a sequence of red, black, yellow, and green at one end and should be inserted into the plug
of the EVB at the other end. Among the 4-pin cables:
⚫Green

To use the UART function, install the USB-to-UART driver (PL2303) first. If an MCU is used to control
the module, connect the as shown in the following figure:

4 Commissioning
N51 can be commissioned either through a serial port or a USB port. This chapter describes how to
connect the module and how to implement commissioning through either port.
4.1 Through Serial Port
Step 1: Connect the EVB board and start it.
1. Connect it to the computer through the M5X0-PWR board.
2. Use the 5V adapter to supply power and push the power switch to the ON side.
3. Hold the PWRKEY_N button for 5 seconds, and the module starts up.
Step 2: Install the PL2303 driver.
Obtain the driver package from Neoway FAE or download it from the Internet if you use the
serial-to-USB cable Neoway provided.
Step 3: Start the Neo_ComTool and send AT commands.
