Description

The Freenove ESP8266 development board has an ESP-12S 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-12S module has an ESP8266EX SoCSystem On a Chip (Datasheet PDF) with a 32-bit Single-Core processor that can run from 80MHz to 160MHz, contains 4MB 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), and has a built PCBPrinted Circuit Board antenna.

The board has pins that break out the ESP-12S peripheral interfaces (11x 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). This board also includes a reset button, bootloading button, and four LEDLight Emitting Diodes. One LED is for power, one is user controllable, and the other two are for (TXTransmit,RXReceive) communication.
