4.2.Reference Design
The latest schematic and design examples, bill of material, and layout file are available fromoriginal developer . Contact us for details.
Figure 1: Module Reference Design

Circuit Description
1. VBAT supply voltage value is 1.80V-3.60V.
2.Every GPIOs can be used as a wake-up pin, and can be configured as a high-level or low-levelwake-up interrupt.
3.The module can support up to 8 PWM output channels, any GPIO can be configured for PWM
function.
4.The PIN12 (RESET) pin is active low, and the internal 10K pull-up. General applications need tobe suspended. If the RESET pin is used, must consult Pairlink for recommendations.
5.PIN20 (P3_1 / UART_RX), PIN21 (P3_0 /UART_TX) is configured as the module's UART interface
by default.
6.J1 and J2 are development and debugging interfaces, that need to be reserved if the PCB spaceis sufficient-8www.pairlink.com.cn

4.3.Appearance and Dimensions
Figure 2 shows the size of the module.The components and prominent structure are not allowed
put in this size range(20.5mm*14.0mm*2.6mm).
The following land pattern size is recommended for user board design. However, user can modify
it according PCB soldering conditions. Sufficient examination is necessary if use the modified
land pattern.

4.4.Module Layout Guideline
The layout on user PCB should be designed according to the following guideline.
When the module is placed on the PCB, it must be ensured that the RF antenna area (2 times thewidth of the module) is hollow or suspended, and there must be no traces, vias or copper.
