Wireless-Tag’s WT99P4C5-S1 is a versatile multimedia development board built around the WT0132P4-A1 core module, which integrates Espressif’s ESP32-P4 dual-core RISC-V SoC. According to the company, this board targets applications such as AIoT, Human-Machine Interfaces, and edge computing, offering extensive connectivity, audio features, and multimedia expansion options.

The ESP32-P4 runs dual RISC-V cores at up to 400 MHz and supports AI instruction extensions, a single-precision FPU, and a low-power sub-core running up to 40 MHz for energy-efficient tasks. Developers have access to a memory subsystem with on-chip SRAM, external PSRAM, up to 16 MB of Flash, and a MicroSD card slot for additional local storage.

Wireless connectivity is provided by the ESP32-C5-WROOM-1 module, which supports dual-band 2.4 GHz/5 GHz Wi‑Fi 6 and BLE 5.3, while wired connectivity includes 10/100 Mbps Ethernet through an onboard PHY and RS-485 via an SIT3088EESA transceiver.

For audio applications, the board integrates an ES8311 audio codec with a low-noise pre-amp, headphone driver, and analog mixing, plus an NS4150B Class-D amplifier to drive speakers through a dedicated output port, while a built-in microphone connects directly to the codec. The WT99P4C5-S1 exposes a wide range of interfaces, including 55 programmable GPIOs, SPI, I2C, I2S, ADC, PWM, and UART.

Multimedia expansion is supported through MIPI CSI for camera modules and MIPI DSI for display panels, alongside an LCD TP connector for touch interfaces. Multiple USB 2.0 ports are available, including USB-to-UART for debugging (via a CP2102N bridge) and separate full-speed and high-speed USB OTG connections through Type-C and Type-A ports.

Power management features include onboard 5 V to 3.3 V regulators and headers like J5, J6, and J14 for breaking out GPIOs. A physical boot/reset button, RJ45 Ethernet port, and dedicated power switch round out the hardware.
