AnalogLamb's TinyML Maple Eye ESP32-S3 Is a Dual-Screen Alternative to Espressif's ESP32-S3-EYE
Equipped with a 2MP camera, dual displays, 8MB of PSRAM, microSD, Wi-Fi, Bluetooth, and more, this is a feature-packed edge AI dev board.
Beijing-based AnalogLamb has announced a tinyML and edge AI development board built with computer vision in mind, pairing an Espressif ESP32-S3 with two-megapixel camera sensor, a microphone, and two compact on-board color displays: the Maple Eye ESP32-S3.
"The Maple Eye ESP32-S3 is a small-sized AI development board produced by AnalogLamb," the company writes of its board design, also known as the Maple Eye Alef. "It is based on the ESP32-S3 SoC and ESP-WHO, Espressif’s AI development framework."
The heart of the board, brought to our attention by CNX Software, is an Espressif ESP32-S3 system-on-chip, which includes two Tensilica Xtensa LX7 microcontroller cores running at 240MHz plus vector extensions for tinyML and edge AI acceleration and 512kB of internal static RAM (SRAM) — to which AnalogLamb has added 8MB of pseudo-static RAM (PSRAM) plus 8MB of flash memory.
The board includes 2.4GHz 802.11b/g/n Wi-Fi and Bluetooth 5 Low Energy (BLE) connectivity, 45 general-purpose input/output (GPIO) pins with functionality including SPI, I2C, I2S, and UART buses, pulse-width modulation (PWM), SDIO Host, analog inputs, and a two-wire automotive interface (TWAI) controller, plus a USB 1.1 On-The-Go (OTG) interface and USB-UART bridge support.
It's the camera that's the key feature, however. An OV2640 sensor, the on-board camera offers a relatively low two-megapixel resolution with support for wireless or USB streaming and display on either of the board's built-in displays — one located on the top for traditional camera operation, and one on the bottom for selfie-style use. Alongside the camera sensor is a digital microphone, a three-axis accelerometer, and a microSD interface — plus four user-programmable buttons and support for battery operation.
For the software side of things, AnalogLamb has based its board on Espressif's ESP32-S3-EYE reference design — meaning it's compatible with the same software, including the ESP-WHO facial-detection framework.
The board is now available to pre-order on the AnalogLamb website at a discounted $19.99, ahead of an early May released date — at which point the price will likely jump to a claimed target retail price of $47 per unit.
