ESP-01S Board only

Description

This is an unprogrammed ESP-01 used in my WLED projects but you can program any project with it. I recommend the programming jig to make life a bit easier.

Features:
SDIO 2.0, SPI, UART
Wi-Fi Direct (P2P), soft-AP
Integrated TCP/IP protocol stack
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 SDIO 1.1/2.0, SPI, UART STBC, 1×1 MIMO, 2×1 MIMO A-MPDU & A-MSDU aggregation & 0.4ms guard interval Integrated RF switch, balun, 24dBm PA, DCXO, and PMU Integrated MAC/baseband processors Quality of Service management 1MB Flash compared to to ESP-01 512kb Specification: 802.11 b/g/n Wake up and transmit packets in < 2ms Standby power consumption of < 1.0mW (DTIM3)
