DESCRIPTION

Grove - UART WiFi is a serial transceiver module featuring the ubiquitous ESP8266 IoT SoC. With integrated TCP/IP protocol stack, this module lets your microcontroller interact with WiFi networks with only a few lines of code. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning you can send simple text commands to control the device. The SoC features integrated WEP, WPA/WPA2, TKIP, AES, and WAPI engines, can act as an access point with DHCP, can join existing WiFi networks and has configurable MAC and IP addresses.

FEATURES

Grove 4-pin connector (RX,TX,VCC,GND) 802.11 b/g/n protocol (2.4GHz) WiFi Direct (P2P), soft-AP Supports three modes: AP, STA and AP+STA coexistence mode Integrated TCP/IP protocol stack LwIP (lightweight IP) Integrated low power 32-bit CPU could be reprogrammed as an application processor Integrated temperature sensor Serial UART Interface Multi-queue QoS management Wake up and transmit packets in < 2ms Metal shielding Onboard ceramic antenna Reset switch

SPECIFICATION

Input voltage: 3V / 5V Baud Rate: 115200 Based on ESP8266 ESP-07 SoC AT Firmware: esp_iot_sdk_v1.1.0 + Seeed modifications: 2x additional AT commands to control blue Link LED. Register red WiFi LED to the ESP8266 wifi state LED. AT command set SDIO 1.1/2.0, SPI, UART Five power states: OFF, DEEP_SLEEP, SLEEP, WAKEUP and ON. Standby power consumption of < 1.0mW (DTIM=3) Integrated TR switch, balun, LNA, power amplifier and matching network Integrated PLLs, regulators, DCXO and power management units +19.5dBm output power in 802.11b mode Power down leakage current of <10uA Hardware accelerators for CCMP (CBC-MAC, counter mode), TKIP (MIC, RC4), WAPI (SMS4), WEP (RC4), CRC WPA/WPA2 PSK, and WPS driver A-MPDU & A-MSDU aggregation & 0.4ms guard interval Dimensions: 25.43mm x 20.35mm
