3 Power and Connection
Power is supplied for the N27 EVB only through external power cables. The N27 EVK provides one
M5X0-PWR cable and one Micro-USB cable for data communication.
3.1 Power Supply
The N27 EVB provides solder pads for external power cables, as shown in Figure 3-2. The input voltage
ranges from 3.1V to 4.3V and a 3.6V regulated power source is recommended.
Figure 3-1 Power pads
The power source supplies voltage to the module directly in this manner. Do NOT connect the pads reversely or
use a power source exceeding the requirements. 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 N27 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
Module TXD, output, CMOS level
⚫Yellow
Module RXD, input, maximum 3.3 V CMOS level
⚫Black
Ground
⚫Red
VBAT, main power input, 3.6V to 4.5V, 3.8 V recommended
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:
