Wireless-Tag ESP32-Nano WT9932S3-NANO ESP32-S3R8 DevKit

Description

The Wireless-Tag ESP32-Nano Development Kit (model WT9932S3-NANO) delivers a high-performance, ultra-compact platform for IoT edge computing and wireless prototyping. At its core is the Espressif ESP32-S3R8 system-on-chip, which combines a dual-core Xtensa LX7 CPU capable of 240MHz operation with substantial onboard memory—512kB SRAM, 8MB pseudo-static RAM (PSRAM), and 16MB flash—enabling complex firmware and data buffering for sensor networks and edge AI tasks.

Its integrated 2.4GHz Wi-Fi 4 (802.11 b/g/n) and Bluetooth Low Energy 5.0 radio provide dual-mode wireless connectivity, suitable for creating Wi-Fi gateways, BLE beacons, or hybrid mesh nodes. The board’s power architecture supports typical active operating currents for wireless transmission while offering deep sleep modes for battery-powered deployments. The nano form factor (44mm x 18mm) and castellated pad design allow for direct soldering into custom carrier boards or use as a standalone module, making it ideal for space-constrained industrial telemetry, smart home controllers, and wearable tech projects.
