The T5-E1 module provides 16 capacitive sensing GPIOs, and the following table details the pins.

• When using the touch feature, it is recommended to reserve a series resistor close to the module to reduce coupling noise and interference on the line and to enhance ESD protection.
• The recommended resistance value is 470 Ω to 2 kΩ, with 510 Ω preferred. The specific value depends on the actual test results of the product.
• The traces should be as short and thin as possible, with a length less than 300 mm, a width no greater than 0.18 mm, and a trace angle greater than or equal to 90°.
• The spacing between different touch channels should be as far as possible, and they should be away from RF, I2C, SPI, and high-speed signal lines.
• The touch electrodes and traces are surrounded by a grid ground, and the trace clearance from the ground ranges from 0.5 mm to 1 mm.
• The diameter of the touch electrodes ranges from 8 mm to 15 mm.

Mô tả Pin

Ứng dụng

If only one MIC is used, MIC1 must be used.

Nguồn điện

• Khối lượng hoạt độngtage range of the T5-E1 module is 2.0V to 3.6V, with a typical value of 3.3V. The supply current for 3.3V modules must be greater than the maximum input current. The total capacity of the external filter capacitor should be greater than 10 μF.
• Place the filter capacitors C1 and C2 near the power pin of the module.

Pins of the module

• The GPIO might experience an uncontrollable high level within five milliseconds of starting the module (before the program startup). Place a 4.7 kΩ pull-down resistor if needed.
• The RST pin of the module is a hardware reset pin. The module has internal weak pull-up resistors configured. If the pin is not used, it can float. If a module has been paired, this pin cannot be used to clear pairing information.
• The TX1 pin on the module is used to select a mode. Pulling TX1 down before the module is powered on will start the test firmware, while floating it or pulling it up will start the application firmware. In normal use, this pin is used as a log printing port.
• Other unused pins can be left floating.
• For more information about pin configuration, see the module datasheet.

Power-on sequence of the module

• Suppose that the high-level voltage settling time of the module’s GPIO is t2 và tậptage settling time of the module’s power pin is t1. Every time the module is powered on, t2 it must be greater than or equal to t1.

Như thể hiện trong hình sau:

• If t2 là ít hơn t1The module might fail to start.
  • To return the module to its normal state, pull down the module reset pin (RST) for one millisecond and pull up to restart the module.
  • Repeatedly power-cycling the module power pin will not restore it to its normal state.

Thiết kế công suất thấp

Option 1: Control the module power pin on/off

• This circuit design can achieve overall low power consumption.
• Nó hoạt động như thế nào: As shown in the circuit diagram, the MCU can control the switch S1 with the GPIO pin to power on/off the module.
• When the MCU has data to report to the cloud, it turns it S1 on. Then, the module can receive data from the MCU and report data to the cloud and the mobile app.
• When data reporting is completed, the module will be powered off and consume no power.

disadvantages:

1. Current sinking occurs. When the switch S1 is turned off, the TXD and RXD pins on the module are still connected to the RXD and TXD pins on the MCU.
2. Therefore, the current from the MCU can flow into the VCC pin of the module through the UART pin.
3. The TXD and RXD pins of the module are high, so the current sinking will increase the consumption of the module.
4. Khi công tắc S1 is turned on next time, t2 it will be less than t1, which can cause the module to freeze.

Giải pháp 1: Optimize the software of the MCU without hardware modification. When the MCU detects that the data reporting is completed, the program proceeds with the following steps.

1. Set the TXD and RXD pins of the MCU as GPIO pins that are configured as the open-drain or weak pull-down mode.
2. Bật công tắc S1 off to power off the module.
3. This way, when the MCU has data to report, it turns  S1 vào lúc đầu.
4. Then, it configures the TXD and RXD pins as the UART to establish communication with the module for data transmission.

Quan trọng

1. This solution does not apply to MCUs whose UART pin cannot be configured as the open-drain or weak pull-up mode.
2. If the UART circuit has a pull-up resistor, one terminal of the resistor must be connected to the VCC pin of the module, or you can directly remove this resistor.
   • Giải pháp 2: Add a level translator to the circuit without software modification.
   • See the circuit diagram in the preceding sections, Level translator reference, and Connection between a module and a 3.3V MCU, and embed a level translator in the UART circuit.

Option 2: Reduce power usage in the idle state

• Pull down the module’s RST pin to reduce idle consumption.
• Nó hoạt động như thế nào: As shown in the circuit diagram, the MCU can control the RST pin with the GPIO pin to power on/off the module.
• When the MCU has data to report to the cloud, the GPIO outputs high to power on the module. Then, the module can receive data from the MCU and report data to the cloud and the mobile app.
• When data reporting is completed, the GPIO outputs low and the module runs in reset mode with low power consumption.
• disadvantage: The RST pin has a 10 kΩ internal pull-up resistor, so the module has an input current of 330 μA in the reset mode.

Radio frequency RF test

The antenna is susceptible to the distance from the shell to the surrounding components. We recommend that you test the RF performance after the final test.
The RF test items and metrics are listed in the following table.

• TRP and TIS must be tested in a dark chamber of the antenna manufacturers or certified organizations.
• The test items apply to most Wi-Fi products, excluding certain special products.

Ăng-ten

Antenna clearance

• Do not use metal shells or plastic shells with metallic paint or coating in the direction of the antenna radiation. Do not use metal objects such as screws and rivets near the antenna, which might affect the antenna’s efficiency.
• The distance between the antenna and other mental components should be at least 15 mm.
• Try to increase the distance from the top shell to the antenna to minimize the impact on antenna performance.
• Try to increase the distance from the upper and bottom shells to the antenna to minimize the impact on antenna performance.
• Keep the module away from speakers, power switches, cameras, HDMI, USB, and other high-speed signals to avoid interference.
• Avoid metal shielding near the antenna. If co-channel interference occurs, you must evaluate the impact on the antenna performance and ensure isolation from interference.
• According to the antenna shape of the T5-E1 module, you can choose Position 3 or Position 4 (optimal) when using the module.
• That is to say, the antenna feed point should be as close to the edge of the board as possible. The position marked with a red dot in the figure below shows where the T5-E1 antenna feed point is.
