HOW DOES IT WORK?
IoT ExpressLink Click is based on the ESP32-C3-MINI-1-N4-A, a general-purpose 2.4GHz WiFi (802.11 b/g/n) and Bluetooth® 5 LE combo module from Espressif Systems that comes with an onboard PCB antenna. This module's core is the ESP32C3 series of SoC RISCV single-core 32-bit microprocessor (ESP32-C3FN4), a chip with an embedded flash of 4MB and a clock speed of up to 160MHz. Since flash is packaged in the ESP32-C3FN4 chip rather than integrated into the module, the ESP32-C3-MINI-1-N4-A has a smaller package size. Thanks to its rich set of features necessary to implement IoT ExpressLink services, this Click board™ is ideal for smart homes, industrial automation, health care, consumer electronics, and generic IoT sensor hubs and data logger applications.
The IoT ExpressLink Click interfaces with a host MCU through UART communication, which involves sending AT commands using RX and TX pins operating at a rate of 115200bps. Besides the UART pins, this Click board™ also employs other pins of the mikroBUS™ socket to enhance its functionality. For example, the WK pin is utilized as a module wake-up pin, the EVT pin detects significant events during operation, and the device enable pin RST offers a switch operation to turn ON/OFF the module.
On the left side of the board, it is possible to find an additional unpopulated header that offers full support for debugging and programming capabilities. With this header, the user can use a JTAG interface for programming and debugging, available through the JTAG interface pins (TDO, TCK, TDI, and TMS). On the right side of the board, there is also a set of unpopulated headers like extra UART pins for debugging and a header with user-configurable general-purpose I/O pins.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
