⚡ WT99P461-S1: ESP32-P4X/C61 board at $21

Wireless Tag has released the WT99P461-S1, a $21 development board combining the ESP32-P4X and ESP32-C61. This full-featured kit targets industrial HMIs, gateways, and control applications requiring robust connectivity and multimedia capabilities.

The board utilizes the WT01P461-S1 module, identical to the one found on the ESP32P4C61-TINY. Key additions include Fast Ethernet, RS-485, CAN bus, an on-board microphone, and a speaker connector. It retains support for microSD cards and MIPI DSI/CSI interfaces for display and camera integration.

The ESP32-P4X features a dual-core RISC-V microcontroller running at 360 or 400 MHz with AI instructions and a single-precision FPU. A low-power RISC-V core operates at up to 40 MHz. Graphics acceleration is handled by a 2D Pixel Processing Accelerator, while video support includes H.264 and JPEG codecs.

Memory resources comprise 768 KB of HP L2MEM, 32 KB of LP SRAM, 8 KB of TCM, and 32 MB of PSRAM. Storage includes 128 KB of HP ROM. The design integrates WiFi 6 capabilities via the ESP32-C61 companion chip, offering a comprehensive solution for embedded systems needing high-performance processing and diverse industrial interfaces.
