Waveshare ESP32-P4-Module-DEV-KIT
Highest-capability microcontroller board in this workbook. ESP32-P4 RISC-V dual-core plus a single-core low-power unit; 128 KB HP ROM, 16 KB LP ROM, 768 KB HP L2MEM, 32 KB LP SRAM, 8 KB TCM; 32 MB PSRAM in the chip package; onboard 16 MB NOR flash. Hardware JPEG codec, pixel processing accelerator, image signal processor and H.264 encoder. MIPI-CSI and MIPI-DSI 2-lane, USB 2.0 OTG high speed (host or device by jumper), 100M Ethernet with RJ45, SDIO 3.0 TF card slot, onboard microphone, MX1.25 speaker header for an 8 ohm 2 W speaker, RTC battery header, 40-pin GPIO header with 28 programmable GPIOs, reserved PoE module header (PoE module not included). A built-in ESP32-C6 provides Wi-Fi 6 and Bluetooth 5 LE over SDIO. Secure Boot, flash encryption, crypto accelerators and TRNG.
Seeed Studio XIAO ESP32S3
XIAO ESP32S3 with a sensor expansion board adding a camera sensor, a digital microphone and a microSD slot supporting 32 GB FAT. 8 MB PSRAM and 8 MB flash on chip, adds I2S and a B2B connector with two extra GPIOs. 21 x 17.8 x 15 mm with the expansion board. CONTRADICTION ON THE MANUFACTURER PAGE: the specification table says OV3660 while the feature list says 'detachable OV2640 camera sensor for 1600x1200'. The camera part number is therefore unresolved.
