Description

The DFRobot FireBeetle ESP8266 (SKU:DFR0489) is low-power consumption development board designed for IoTInternet Of Things, with an ESP-12F module for 2.4GHz 802.11IEEE 802.11 is a set of protocol standards that define communication for a Wireless Local Area Network (WLAN). In order for WiFi to work between different devices, they all need to agree on how they are going to communicate. The current version of the standard is IEEE 802.11-2007, with many amendments such as 802.11a, 802.11b, 802.11g, and 802.11n.b/g/n WiFi up to 72.2Mbps that supports APA WiFi Access Point (AP) is a device that creates a wireless local area network, or WLAN, and acts as a central hub that allows other devices, such as smartphones or computers, to connect to it over WiFi./ STAA WiFi Station (STA) is a device that has the capability to connect to an existing WiFi network as a client in the same way other devices, such as smartphones or computers, join an established network and communicate with other devices on that network or access the internet./AP+STAA WiFi device in AP+STA mode acts as both an Access Point (AP) as well as a Station (STA), where the device can connect to an existing network as a client (STA) while simultaneously hosting its own network (AP) for other devices to connect to. modes.

The ESP-12F module has an ESP8266EX 32-bit SoCSystem On a Chip (Datasheet PDF) that can run from 80MHz (default) to 160MHz and contains 16MB flash memory (enough to support OTAOver-The-Air (OTA) updates, also known as OTA programming, are wireless updates that are delivered to embedded systems. programming updates). The board has pins that break out the ESP-12F peripheral interfaces (10x Digital I/OInput/Output with PWMPulse-Width Modulation, 1x Analog Input) and communication interfaces (UARTUniversal Asynchronous Receiver-Transmitter/I2CInter-Integrated Circuit. Also referred to as IIC or I²C./SPISerial Peripheral Interface/I2SInter-IC Sound).

The FireBeetle has a Micro-B USB connector with a CH340 chip for data, programming, and power. The board can also be powered (3.3V to 5V) using the JST XH2.54mm battery connector with single cell Li-ionLithium-ion/LiPoLithium Polymer batteries, which also has built-in battery charging using the TP4056 chip when powering the board over USB. There appears to be two versions of this board that have the battery connector either horizontal or vertical (probably so it doesn't get in the way of plugging in the USB).

The FireBeetle also includes a reset button and LEDLight Emitting Diode to indicate the battery connection or charge status. The LED blinks if the battery is not connected, is constantly on when the battery is charging, and off when battery is completely charged. The size of the board is 53mm x 24mm (2.09in x 0.94in).
