HOW DOES IT WORK?
ESP8684 Click is based on the ESP8684-MINI-1, a highly integrated WiFi, and a Bluetooth 5 module from Espressif Systems. It is based on the ESP8684H2 embedded 32-bit RISC-V single-core processor operating at up to 120MHz frequency. The processor also has an on-chip 576KB of ROM and 272KB of SRAM memory, supporting flash in-circuit programming (ICP). It also features an internal co-existence mechanism between WiFi and Bluetooth to share the same printed PCB antenna. The downside is that you can't use both WiFi and Bluetooth at the same time.
ESP8684 Click is an IEEE802.11b/g/n-compliant and supports 20MHz bandwidth in the 2.4GHz band. In 1T1R mode, it can achieve data rates of up to 72.2Mbps. In addition, the module supports WiFi Multimedia (WMM), fragmentation and defragmentation, transmit opportunity (TXOP), automatic beacon monitoring hardware (hardware TSF), and more. As for Bluetooth, the module can achieve speeds of 125kbps, 500kbps, 1Mbps, and 2Mbps. The security features secure boot, flash encryption, 1024-bit OTP up to 256 bits for use, cryptographic hardware acceleration, and more.
This Click board™ is equipped with a USB type C connector and circuits that allow you to establish direct communication between the ESP8684 module and a PC. This communication can be used for testing purposes or for upgrading the software. For uploading software to the ESP8684 module, there is an auto-reset circuit and the CP2102N, a USB-to-UART bridge from Silicon Labs. Two LEDs, RX and TX, are there to confirm the data exchange over this bridge visually. In addition, two buttons, RESET, and BOOT, allow you to enter the ESP8684's boot mode. Finally, a header contains 3 GPIOs and a GND for user configuration and can be used for an analog interface.
ESP8684 Click uses a standard 2-Wire UART interface to communicate with the host MCU with commonly used UART RTS and CTS control flow pins. Besides the available software and libraries we provide, you can use a set of AT commands to program the ESP8684 module. In addition to the UART bridge and two onboard buttons, you can enter the ESP8684's boot mode via RST and BT pins of the mikroBUS™ socket. Thanks to the onboard NCP1117 LDO, which converts USB voltage into the 3.3V necessary for operation, this board can be standalone independent of the mikroBUS™ socket.
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.
