UDOO is known for its x86 boards which integrate an Arduino compatible microcontroller, but the UDOO key is different, as it does without an Intel or AMD processor, and instead combines the Raspberry Pi RP2040 microcontroller with Espressif ESP32 WiFi & Bluetooth WiSoC.
As we have noted in the past, combining Raspberry Pi Pico / RP2040 with ESP32 doesn’t make much sense in most cases, but here is the UDOO KEY will be offered for just $ 4 for the first 1000 units, so they’ll basically launch the ESP32 for free since it’s the same price as a Raspberry Pi Pico, before eventually selling the device for $ 20.
UDOO Key Specifications:
- Arm Cortex-M0 + Dual-Core MCU Raspberry Pi RP2040 @ 133MHz Microcontroller with 264KB SRAM On-Chip
- Storage – 8MB QSPI Flash for RP2040
- Wireless module – ESP32-WROVER-E with ESP32-D0WD-V3 Dual-core WiFi + Bluetooth SoC, 16MB SPI flash and 8MB PSRAM
- Sensor – 9-axis IMU, microphone. and on-chip temperature sensor (RP2040)
- USB – USB Type-C port for power and programming
- Raspberry Pi Pico headers compatible with 26 GPIO, 3x 12-bit ADC up to 500 Kbps, 2x UART, 2x I2C, 2x SPI, 16x PWM, 2x high speed programmable I / O
- UEXT connector connected to ESP32, compatible with Olimex modules
- Miscellaneous – 2x button for RP2040, one button and 2x RGB LED for ESP32
- Power supply – 5V via USB-C port
- Dimensions – 130 x 40 mm
The RP2040 section of the board follows the Raspberry Pi Pico form factor to be able to reuse accessories and expansion boards, while the larger ESP32 section comes with a UEXT connector with I2C, SPI and UART interfaces to support directly charges Olimex modules or other modules via jumper cables.
UDOO explains that the board is designed for AI applications on RP2040 or ESP32 with TinyML, TensorFlow Lite, MicroPython, C / C ++ or the Arduino IDE. The UDOO KEY also supports Clea IA IoT platform designed “to deploy AI models and applications to a fleet of IoT devices via live updates.” Clea-based is being developed by embedded systems company SECO, which happens to be the parent company of UDOO, and should explain the losing proposition of selling the first units of the card for just $ 4. The solution is based on two open source projects with ESP-IDF-based Astarte allowing developers to manage and process IoT data, while Edgehog enables fleet device management and ESP32 OTA updates.
SECO comes from launched the table on Kickstarter for as little as $ 4 each, but only for the first 1000 coins, and without the IMU or microphone that comes with the $ 9 UDOO KEY PRO. The table may end up being mostly interesting for European or North American users, because shipping to Italy is $ 6, while the rest of Europe, United States and Canada pay $ 9, and shipping drops to $ 15 to the rest of the world, which suddenly makes the plateau a lot less interesting. Deliveries are expected to start in January 2022.
