4. Peripheral Interface

4.1. GPIO

There are a total of 22 GPIO, please refer to Table 2 for pin definitions.
4.2. UART

This module has two UARTs: UART0 and UART1. To use UART, the pull-up power supply of UART needs to be set to the same power rail as VCC to prevent VCC from running out of power. If UART has high voltage backflow, it may cause internal logic problems in the chip. Alternatively, an anti backflow diode can be added to the pull-up power supply of UART to avoid this problem.

4.2.1. UART0

UART0 is used for burning and debugging purposes, as shown in Table 4.

Note: Main power supply VCC (pin16), main GND (pin18). Except for the first burning of the chip, for each subsequent burning, the Boot pin (pin36) needs to be pulled to the ground before powering on, and then left hanging after burning.

a) Apply 5V working voltage to Bluetooth; b) Adjust the temperature of the temperature box to 65 ± 2 , and after the temperature stabilizes, Bluetooth will work continuously for 500 hours; c) Connect Bluetooth 20 times and findmy 20 times at intermediate points of 100h, 200h, 300h, and 400h respectively; d) After the 500h test is completed, the success rate of connecting the test module in the east, south, west, and north directions at a distance of 20 meters is recorded, and the maximum distance that can be connected is recorded; Note: During the intermediate inspection process, the module can be removed to the outside of the temperature box for a 20 meter distance connection test
10.8.2. Qualification determination
During and after the experiment, the Bluetooth connection was 100% successful, and the findmy connection was 100% successful.

10.9. Input Power Short Circuit Test - Conducted with the Whole Machine

10.9.1. Test method a) Power the Bluetooth module according to the internal power supply method of the battery,
and short-circuit the power input terminal; b) Short circuit for 5 minutes or only until the input voltage drops to 0; c) After the experiment, remove the short-circuit device and power on the Bluetooth module
again; Note: The battery pack is tested, and single modules are not tested
10.9.2. Qualification determination a) The Bluetooth module has no burning phenomenon (allowing protection devices such as
fuses to operate, without causing open flames in surrounding devices); b) The BMS board functions normally and cannot affect the battery output performance.
10.10. Output Short Circuit Test - Conducted with the Whole Machine

10.10.1. Test method
a) Power the Bluetooth module according to the internal power supply method of the battery, and short-circuit the internal power supply of the module;
b) Short circuit for 5 minutes or only until the power output voltage inside the board drops to 0;
c) After the experiment, remove the short-circuit device and power on the Bluetooth module again.
Note: The battery pack is tested, and single modules are not tested

10.10.2. Qualification determination a) The Bluetooth module has no burning phenomenon (allowing protection devices such as
fuses to operate, without causing open flames in surrounding devices); b) The BMS board functions normally and cannot affect the battery output performance.
10.11. Static electricity test
10.11.1. Test method a) Separate module, powered by a 3.3V power supply; b) Voltage level: Contact ± 2kv, 10 times each; Air ± 4kv, 10 times each;

c) Discharge position: shielding cover - contact discharge; Antenna air discharge; Pin (randomly select 10 pins) - contact discharge;
d) After each discharge, it is necessary to discharge through a discharge resistor, and at the same time, connect Bluetooth and Findmy at close range through a mobile phone. If they cannot be connected, the test will be terminated;
e) If the Bluetooth and Findmy function tests are qualified during the static electricity test, after the test is completed, the success rate of connecting the test module in the east, south, west, and north directions at a distance of 20 meters should be recorded, and the maximum distance that can be connected should be recorded;
Note: The actual discharge position can be adjusted based on the physical condition and should be clearly noted; There are other discharge level requirements in the module specification book, which can be adjusted by referring to the specification book.
10.11.2. Qualification determination
During and after the experiment, the Bluetooth connection was 100% successful, and the findmy connection was 100% successful.
10.12. Interference Test

10.12.1. Test method a) Power the Bluetooth module with a voltage of 3.3V and connect it to the working power
supply; b) In the office building environment, multiple devices coexist: WIFI Conduct connection
testing in environments with multiple Bluetooth devices enabled; c) Connect Bluetooth and findmy 20 times at a distance of 20 meters using testing tools; d) Test the success rate of connecting modules in the east, south, west, and north directions at
a distance of 20 meters, and record the maximum distance that can be connected;
10.12.2. Qualification determination
During and after the experiment, the Bluetooth connection was 100% successful, and the findmy connection was 100% successful.
10.13. Packaging and transportation requirements

10.13.1. Package
The products should be packaged with woven tapes, and each product should be located in a different woven tape cavity. Each woven tape should be neatly and orderly placed in the packaging box, and there should be partitions between each woven tape to avoid collision damage. The outer

box should be packaged in cardboard boxes or other boxes. In special circumstances, it can be determined according to the requirements of the demander (contract).

10.13.2. Transport
When handling packaging boxes containing products, they should be handled with care and not thrown. During transportation, it should not be exposed to sunlight or rain, and it is strictly prohibited to mix and transport with flammable materials and active chemicals.
10.13.3. Storage
The product should be placed indoors in a dry, ventilated, and rain and snow resistant environment. The indoor temperature should be between 18  and 28 , and the humidity should be between 35% and 75%. It should not be stored together with corrosive substances such as acids, alkalis, or dusty items. The box containing the product should be properly placed and cushioned.
