Pin Function FAQ for BLE113-A-M256K:

Q: What is the function of pin 1 (VDD)? A: Pin 1 is the power supply input pin. It provides a 3.3V power source to the module.

Q: What does pin 2 (GND) represent? A: Pin 2 is the ground pin, completing the electrical circuit by connecting to the ground of the power supply.

Q: Can I use pins P0.0 to P1.7 for digital inputs/outputs? A: Yes, pins P0.0 to P1.7 are general-purpose I/O pins that can be configured for digital input or output.

Q: What is the role of pin 19 (TXD)? A: Pin 19 is used for UART transmission, sending data out from the BLE113 module.

Q: How does pin 20 (RXD) function? A: Pin 20 is used for UART reception, allowing the BLE113 module to receive incoming data.

Q: What is the SPI_CLK (pin 21) used for? A: Pin 21 is the clock signal for the SPI interface, which synchronizes the data transmission between the master and slave devices.

Q: Can I connect external components to the SPI pins? A: Yes, pins 21 (SPICLK), 22 (SPIMISO), 23 (SPIMOSI), and 24 (SPICS) are for SPI communication and can connect to external devices.

Q: How do I reset the module? A: Pin 25 (RESET) is used to reset the BLE113 module. You can pull this pin low to initiate a reset.

Q: What does the IRQ pin (pin 26) do? A: The IRQ pin is used for interrupt handling. It signals when an event requires attention or processing.

Q: What is the function of pin 27 (VDDIO)? A: Pin 27 provides the voltage supply for the I/O pins. Typically, it's set to the same voltage as VDD (3.3V).

Q: How does the VBUS pin (pin 28) work? A: Pin 28 is used for USB power or detection, providing voltage from the USB bus or enabling detection of a USB connection.

Q: What are the antenna pins (ANT1 and ANT2) for? A: Pins 29 and 30 are used for connecting antennas to the BLE113 module, enabling Bluetooth Low Energy communication.

Q: Can I debug the module using the SWDIO and SWCLK pins? A: Yes, pins 31 (SWDIO) and 32 (SWCLK) are used for debugging the module via Serial Wire Debug (SWD) interface.

Q: How can I use the SPI interface for communication? A: You can use pins 21, 22, 23, and 24 to set up an SPI interface for communication with external devices.

Q: Are the GPIO pins P0.0 to P1.7 5V tolerant? A: No, the GPIO pins are typically 3.3V logic level, and exposing them to higher voltages could damage the module.

Q: Can the TXD and RXD pins be used for I2C communication? A: No, TXD and RXD are for UART communication. I2C communication uses different pins for SDA and SCL.

Q: How can I use pin 25 (RESET)? A: Pin 25 can be pulled low (GND) to reset the BLE113 module, restarting its operation.

Q: Can I power the BLE113 module through USB? A: Yes, pin 28 (VBUS) can be used to supply power from a USB connection.
