ESP-01S WiFi module

The ESP-01S ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP-01S module comes pre-programmed with AT command set firmware. ESP-01S is an extremely cost effective module with a huge, and ever growing, community.

• +19.5dBm output power in 802.11b mode
• Power down leakage current of <10uA
• 1MB Flash Memory
• Integrated low power 32-bit CPU, can be used as application processor
• SDIO 1.1 / 2.0, SPI, UART
• STBC, 1×1 MIMO, 2×1 MIMO
• A-MPDU & A-MSDU aggregation & 0.4ms guard interval
• Wake up and transmit packets in < 2ms
• Standby power consumption of < 1.0mW (DTIM3)

Notes:

1. This module is not capable of 5-to-3V logic-level shifting and will require an external Logic Level Converter. Do not power it directly from your 5V dev board!
2. Note that this module is not FCC-approved.
