Future Hardware Platforms

This page should be a starting point for a discussion on: "What's the next primary Platform for RIOT?"

Constraints

• RIOT is currently unable to run on a platform with more than one core
• RIOT currently support 16 and 32 Bit based hardware

must have / must support

• ARM based
• low power platform
• one wireless interface
• some sort of sensors to play with or accessible I/O ports (such as SPI, I2C etc.)
• device capabilities should match a Class 2 device according to Terminology for Constrained Node Networks
• USB for flashing

should have

• first radio is 802.15.4 compliant
• second radio with more throughput than 802.15.4 (perhaps 802.11?)
• 32 bit based platform (easier to find) / 16 bit based follows
• an EXISTING community around this hardware
• not so expensive (50 € per device?)
• energy measurement feature
• open source hardware / software already existing

nice to have

• Ethernet for debugging, logging, administration

candidates for RIOT

Arduino due

• shop
• no radio, no sensors -> buy extra
• not so cheap
• no energy measurement support?
• fits to our requirements in the most points

Thinkerforge

• shop
• no radio, no sensors -> buy extra
• no energy measurement support?
• not so cheap

Raspberry Pi

• specs
• not a low power platform
• no radio, no sensors -> buy extra
• no energy measurement support?
• too much ram/rom
• biggest community
• cheaper than the others
• ethernet

Modules from Dresden Elektronik

• adapter board deRFsam3
• Cortex-M3 (ARM 32 bits) + 802.15.4 radio chip (AT86RF231)
• Base module is ~30 EUR, but power + serial + JTAG connectors need to be soldered/added
• Many variations of the board and addons: including processor ARM7 / ATmega / ..., radio 800-900 Mhz / 2.4 Ghz, form factor (USB), extension boards, ... so the right(s) one(s) should be carefully selected, and the final price will be higher
