MIOT1 - Computer Module for Internet of Things Applications
The MIOT module is designed to meet the requirements of customers wanting to implement solutions targeting Internet of Things, and general embedded applications. Some of the key considerations, and requirements for such projects are:
Performance - MIOT1 features a ARM cortex A9 processing core with flexible clocking scheme from 25Mhz up to 1Ghz. This flexibility makes MIOT1 suitable for running high level operating systems like Ubuntu Linux and Android Lollipop, or running bare metal applications that only require lower frequencies .
Low Power - Maximising battery life and reducing standby power are often important design requirements. MIOT1 is designed to operate from a 2.9V to 3.3V power supply making it suitable for battery operation. Dynamic frequency and voltage scaling (DVFS) is supported on the module to reduce power consumption when possible. The module also supports ultra lower power states (sub 75mW) while retaining memory contents.
Integrated storage - MIOT1 has the option of uSD card storage or soldered down eMMC memory. Both interfaces support high speed operation at 832 Mbps in UHS-I mode, with theoretical capacities up to 2TB.
Integrated connectivity - MIOT1 features 10/100 Ethernet including Physical layer for high speed wired networking. For wireless networking , WiFi connectivity is provided with support for 802.11abgn in both the 2,4Ghz and 5Ghz bands. Both station and access point modes are supported. The module also includes Bluetooth / BLE connectivity. A USB 2.0 Device and USB 2.0 Host port supporting HS / FS / and LS operation are available.
Flexible peripheral pins - MIOT1 exposes 60 peripheral pins on gold pads around the perimeter of the board. These pins can be individually configured as GPIO pins, or as special function peripheral pins. Supported peripherals include, 18bit TFT LCD interface, UART, SPI, I2C, SDIO, BT.656 camera, I2S, SPDIF. Each pin can be configured individually to either 1.8V or 3.3V levels removing the requirement for external level conditioning.
Small footprint - MIOT1 measures only 38.1mm x 28mm making it ideal for projects where space is a premium.
Low Cost - Always important is cost. MIOT1 is competitively priced and is also designed reduce the total cost of a product. Connectors are often costly, and being high density can have challenging manufacture requirements. As MIOT implements connectivity by use of gold pads on the edge of the board this cost is removed while also providing a more reliable connection to the host board. WiFi is implemented with a layout to minimise / remove the requirement for R&TTE testing which can be costly. Typically only a 4-layer host board is required to implement a solution with MIOT1. The module is suitable for SMT reflow soldering or hand soldering.
Software support - MIOT1 supports Embedded Linux, and Android Lollipop. Support for Microsoft WEC2013 is planned.
