Pin Name PinNo. I/O Description Min. Typ. Max. Unit
VBAT 6 PI 6 PI Power supply for the module 3.0 3.3 3.6 V
GND 8

4.1.1.Reference Design for Power Supply
The module is powered by VBAT, and it is recommended to use a power supply chip that can provide more than 0.3 A output current. For better power supply performance, it is recommended to parallel a 22 pF decoupling capacitor, and two filter capacitors (1 pF and 100 nF) near the module’s VBAT pin. In addition, it is recommended to add a TVS near the VBAT to improve the surge voltage bearing capacity of the module. In principle, the longer the VBAT trace is, the wider it should be.

VBAT reference circuit is shown below:

4.2. Turn On
After the module VBAT is powered on, keep the CEN pin at high level to realize the automatic startup of the module.

The reference design for resetting the module are shown below. An open collector driving circuit can be used to control the CEN pin. Another way to control the CEN is by using a button directly. When pressing the button, an electrostatic strike may generate from finger. Therefore, a TVS component shall be placed near the button for ESD protection. The module reset timing is illustrated in the following figure. 4.4. Download Mode
Keep the input signal of CEN at low level during resetting or power-up and the module will enter download mode.
In the download mode, the firmware can be download through the main UART. During the hardware design, the CEN pin of the module is connected to the RTS of the serial port chip, or the GPIO is controlled according to the following waveform, otherwise the download will fail.
