Reading time: ~5 min
A reference design shaped like the product
From 7 September 2026, Mouser Electronics is stocking Espressif's ESP32-P4X-EYE, a compact vision development kit. The interesting choice here is the enclosure: rather than another rectangular dev board, the kit uses a mini digital camera form factor with a camera, a rear 1.54-inch SPI LCD, a digital microphone, a rotary encoder and a push switch integrated into one shell.
For teams building smart surveillance cameras, vision-model detection nodes or HMI panels, a kit that already resembles the end product shortens the path from evaluation to enclosure design.
ESP32-P4: two RISC-V cores at different jobs
The kit is built on the ESP32-P4. Per Mouser's product listing:
- Dual-core 32-bit RISC-V processor running up to 400 MHz
- A 40 MHz low-power RISC-V core for workloads that prioritise energy efficiency over throughput
- Support for up to 32 MB PSRAM
The asymmetric arrangement is the point. Two 400 MHz cores handle image and application work; the 40 MHz core stays resident for always-on duties. That is a materially different power story than parking the whole SoC in a light-sleep state and waking the big cores for every interrupt.
Espressif's Chinese-language distributor announcement for the kit describes the ESP32-P4 as a dual-core 400 MHz RISC-V processor supporting up to 32 MB PSRAM, and lists USB 2.0, MIPI-CSI/DSI and an H.264 encoder among the peripherals — consistent with Mouser's own SoC description, which adds image signal processing, JPEG processing and pixel acceleration.
Wireless comes from a second module
The ESP32-P4 has no radio of its own on this board. Connectivity is handled by an onboard ESP32-C6-MINI-1 module providing Wi-Fi, IEEE 802.15.4 and BLE, with a PCB antenna. Espressif also exposes jumpers so developers can wire peripherals to the board.
That split is worth flagging early in an evaluation. Two firmware images and an inter-processor link are part of the design, not an afterthought — but it also means the radio path is a separately sourced module, which is a reasonable property if you care about long-term availability across multiple suppliers of an open-standard part.
Onboard I/O
The kit ships with enough peripherals to collect multimodal data without a shield:
- Camera
- 1.54-inch SPI LCD (rear-mounted)
- Digital microphone
- Rotary encoder and push switch
- MicroSD card slot
- USB 2.0
Audio plus video plus removable storage on one board makes it a viable platform for multimodal capture at the edge, not just frame grabbing.
Target applications named by the vendors
Mouser and Espressif both position the kit at smart surveillance cameras, vision model detection, IoT edge computing and HMI. The 1.54-inch display and rotary encoder suggest Espressif expects people to build interactive devices, not headless sensors — a menu-driven camera or a portable inspection tool rather than a fixed doorbell.
One thing to check before you commit
Three checks before you commit:
- The silicon is not new. What arrived on 7 September 2026 is the kit and its distribution through Mouser, not the ESP32-P4. SoC maturity is a plus — drivers and community examples already exist — but do not read the kit announcement as a silicon launch. Confirm the current datasheet revision and errata directly.
- Two modules means two firmware targets. The ESP32-P4 and the ESP32-C6-MINI-1 are separate parts with separate roles. Plan the inter-processor link and the OTA story for both images, not one.
- Confirm populated PSRAM. "Up to 32 MB" is an SoC capability, not necessarily what ships on the kit. If your model or frame buffer needs the full 32 MB, verify the specific kit revision.
Not disclosed in the sources used here: kit price, PSRAM size actually populated on the shipping kit (only "up to 32 MB" is stated for the SoC), camera sensor part number and resolution, power consumption, and any inference throughput figures. The kit has no published NPU TOPS figure in these sources, and none should be assumed.

Verification notes
- The 2026-09-07 date is from the EEPW report, which reproduces Mouser's announcement and carries an explicit dateline of "2026年9月7日".
- The 400 MHz dual-core figure, the 40 MHz low-power core, the 32 MB PSRAM ceiling and the peripheral list (MIPI CSI, MIPI DSI, ISP, H.264 encoding, JPEG, pixel acceleration) come from Mouser's own ESP32-P4 SoC product description.
- The kit-level details (1.54-inch SPI LCD, digital microphone, rotary encoder, push switch, MicroSD, ESP32-C6-MINI-1 for Wi-Fi/802.15.4/BLE, PCB antenna, camera form factor) come from the EEPW reproduction of the Mouser announcement.
- Espressif's own product page for ESP32-P4X-EYE was not retrieved during research; no first-party Espressif datasheet was consulted. All figures are attributed to Mouser/EEPW above.
- No pricing, camera sensor specification, power figure or AI throughput number was found in any source. These are marked not disclosed rather than estimated.
