Arduino shield adds AI capability for IoT developments

By Nick Flaherty www.flaherty.co.uk

Lattice Semiconductor has launched a development kit for implementing AI in devices using vision and sound as sensory inputs. The HM01B0 UPduino Shield is a rapid prototyping board, in the Arduino form factor, with the components designers need to quickly develop always-on, low power smart IoT devices.

The $50 kit consists of a Lattice iCE40 UltraPlus FPGA-based Upduino 2.0 board and a Himax HM01B0 image sensor module.

Optimized for IoT devices and embedded AI applications, the iCE40 UltraPlus FPGA has power consumption as low as 75 µW in sleep mode and 1-10mA when active. It also supports I/O port configuration flexibility, including the ability to combine multiple signals for transmission over one port. This helps designers easily investigate and experiment with different designs and to accelerate product prototyping. Proof-of-concept demos such as Human Presence Detection and Hand Gesture Detection are included in this modular hardware platform to further simplify and accelerate vision-based AI systems.

“The Upduino Shield development kit offers substantial flexibility to product developers by making the addition of vision-based AI support to IoT-connected devices quick and easy,” said Peiju Chiang, Product Marketing Manager at Lattice Semiconductor. “And because the kit uses our low-power iCE UltraPlus FPGA, adding AI support to IoT products is possible without significant increase in product power consumption, a key requirement for IoT devices operating at the network Edge.”

Key features of the UPduino Shield development kit include:
  • UltraPlus FPGA with 5.3K LUTs, 1 Mb SPRAM, 120 Kb DPRAM, 8 Multipliers
  • FTDI FT232H USB to SPI Device for FPGA programming
  • 12 MHz Crystal Oscillator Clock Source
  • 34 GPIOs on 0.1” headers for connecting to the adapter board
  • SPI Flash, RGB LED, 3.3 V and 1.2 V voltage regulators
  • Can be used with the new Lattice Radiant Design Software 1.1
