Introduction

ESPC3-20 Wi-Fi and BLE coexistence Module is a highly integrated single-chip low power 802.11bgn Wireless LAN (WLAN) network controller. It combines a RISC CPU, WLAN MAC, a 1T1R capable WLAN baseband, RF, and Bluetooth in a single chip. It also provides a bunch of configurable GPIO, which are configured as digital peripherals for different applications and control usage. ESPC3-20 Module integrates internal memories for complete Wi-Fi protocol functions. The embedded memory configuration also provides convenient application developments. ESPC3-20 module supports the standard IEEE802.11 b/g/n/e/i protocol and the complete TCP/IP protocol stack. User can use it to add the Wi-Fi function for the installed devices, and also can be viewed as an independent network controller. Anyway, ESPC3-20 Wi-Fi module provides many probabilities with the best price.
