{"title":"Espressif ESP8266EX Wi-Fi SoC","handle":"espressif-esp8266ex","url":"/products/espressif-esp8266ex","description":"This highly integrated Espressif Wi-Fi system-on-chip is designed for compact Internet of Things hardware that needs reliable 2.4GHz wireless networking with efficient power usage.The ESP8266EX can run as a standalone application processor or operate as a Wi-Fi adapter for a host microcontroller over SPI/SDIO or UART. When hosting an application, it boots from flash, and its integrated high-speed cache helps improve system performance and memory use.On-chip integration includes antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters and power management modules, helping minimise PCB size and external circuitry. It also includes an enhanced Tensilica L106 Diamond series 32-bit processor, on-chip SRAM, and GPIOs for connecting external sensors and devices.Sold as individual units. Note: not recommended for new designs.Specifications:Protocol: 802.11 b/g/n (HT20)Frequency Range: 2.4GHz ~ 2.5GHz (2400MHz ~ 2483.5MHz)Operating Voltage: 2.5V ~ 3.6VOperating Current: Average value: 80mAOperating Temperature Range: –40°C ~ 125°C","vendor":"SparkFun","product_type":"Wi-Fi SoC","in_stock":true,"options":[],"variants":[{"id":16111,"title":"Default Title","sku":"SF-COM-26983","mpn":"COM-26983","price":2.95,"on_sale":false,"in_stock":true,"available_quantity":500}]}
