Note: S: Power supply pins; I/O: Digital input or output pins; AI: Analog input. RST pin
is the module hardware reset pin; it cannot eliminate module-pairing information.
(1) This pin can only be used as ADC input, cannot use it as normal I/O. when not
using, just connect nothing. When used as ADC input, the input voltage range is
0~1.0V.
(2) UART0 is serial port, during power on progress; this serial port will output some-
thing, which can be ignored.

5 ANTENNA INFORMATION
5 Antenna Information
5.1 Antenna Type
Antenna can be connected only using On-board PCB antenna.
5.2 Reduce Antenna Interference
While using the On-board PCB antenna, in order to have the best Wi-Fi performance,
it’s recommended to keep a minimum 15mm distance between the antenna part
and the other metal pieces.
User’s own PCBA design is recommended NOT to pass any wire, NOT do copper pour
under the region of the module’s antenna, to avoid interferences.

6.3 Production Guide
TYWE3L is available in two sizes, with and without pin headers, depending on the
actual application. Pin size and recommended layout as shown below (unit: mm)
6.4 Production Guide
The storage for the delivered module should meet the following condition:
1. The anti-moisture bag should be kept in the environment with temperature <
30 ℃ and humidity < 85% RH.
2. The expiration date is 6 months since the dry packaging products was sealed.
Cautions:
1. All the operators should wear electrostatic ring in the whole process of produc-
tion.
2. While operating, water and dirt should not have any contact with the modules.
