WiFIRCard – ESP32-S3 Smart Wi-Fi + IR Dual Relay Automation Board (10A, Bluetooth 5, MicroSD, USB-C)

Meet WiFIRCard — a powerful IoT + IR automation board smaller than a credit card, yet packed with everything you need to build smart, connected systems.

Powered by the ESP32-S3 WROOM-1, this compact board combines Wi-Fi, Bluetooth 5.0, dual high-load relays, IR remote learning, and MicroSD storage — all in one reliable, precision-engineered card.

At just $39, it delivers performance usually found across multiple devices — now unified into a single smart automation card.

Built for Reliability

Unlike typical relay boards, WiFIRCard features:

• Open PCB track design for maximum current flow
• Enhanced solder masking for improved durability
• Superior heat dissipation
• High-load stability up to 10A

This ensures long-term performance — even when switching heavy appliances.

Powered by ESP32-S3

At its core is the ESP32-S3 dual-core LX7 processor, delivering:

• Up to 16MB Flash
• Up to 8MB PSRAM
• Fast multitasking
• Low power consumption
• Stable wireless performance

Perfect for smart home systems, industrial automation, IoT dashboards, and DIY innovation.

Engineered for Safety

WiFIRCard includes:

• Opto-isolated relay protection
• High-voltage & low-voltage track separation
• Surge-resistant design

Switch AC appliances confidently without risking your low-voltage circuits.
