The EFM32 is a 32-bit ARM Cortex-M3 core, running at up to 32MHz. Depending on the series, run-mode power consumption varies from 150µA to 200µA per MHz, with sleep currents as low as 20nA to 900nA (with a real 32kHz timer running, not just a real time clock). It includes numerous exciting low power peripherals such as a 150nA UART, autonomous pulse and inductive, resistive and capacitative sensor interfaces, integrated op-amps, 12-bit ADC and DACs, and more.

We also feel it is one the easiest to use Cortex-M3 microcontrollers, with the provided libraries and application notes.

Our first development board is based on the EFM32 “Tiny Gecko” EFM32TG110 processor in a tiny 24-pin DIP form factor (similar to our AVR32 Copper design). Features include:

• 24-pin 0.6inch DIP formfactor
• Optional 32kHz crystal on board
• 0.05 inch pitch 10 pin Cortex-M debug port with serial wire debug (SWD) and serial wire output (SWO)
• Programming over the integrated Gecko boot loader using two GPIO pins (with a USB->serial breakout), with provided buttons on the board to enter boot mode

We feel this board is a perfect development tool for hobbyist projects running on batteries, and as a perfect add-on to Energy Micro’s EFM32 Tiny Gecko starter kit as your design goes to the prototype phase.

Target price is $25. Availability by end of January, 2012.

Our first feature is surrounding energy harvesting – taking very tiny power sources and converting them to useful applications.

Bob over at Ambient Sensors has shown how to use the 40mV-500mV LTC3108 boost converter being powered from a Peltier junction.

You can also find his open source design on Github.

If you had a previous store account or order, and wish to lookup any information pertaining to it, please contact our support at support@stackfoundry.com. All pending orders were either shipped or transitioned manually.

We now have stock of the AVR32 Copper development boards, our best selling item, which is often backordered. Lead times are approximately 3 days depending on options ordered.

Our new products are currently in testing – more updates will be provided soon!

We have a line of new products being released in the coming months as part of our refresh cycle.

First off, the following products are “end of life”.

• Megavore XMega Development Board
• Magnetavore XMega Development Board

There is no replacement in place for these products. If you are still interested in MRAM based hardware, please contact us as we still have inventory.

New products include:

• EntropyKing – LPC1343 based, USB-key formfactor, open hardware design, true random number generator device.
• USB Gadget Collection – Test automation and debug tools for engineers, including a HID input device (make your own kiosk or test stand with big buttons!), digitally controlled voltage regulators, and more
• Ultra-low Power Development Hardware – Including the ARM Cortex-M3 based EFM32 Gecko family of processors.

We will continue selling the AT32UC3B156 based Copper board. If there is sufficient interest, we are discussing including a floating-point version based around the AT32UC3C processor.

Look for our store re-launch soon.

Existing URLs will be redirected as appropriate.

Note that user accounts and previous orders will not be migrated.

Currently moved:

1. qsgen the static site generator
2. TropicSSL the BSD licensed fork of PolarSSL.

More information on supporting boards coming soon!

(And yes, this order was placed over 10 months ago…)

Our stock of AVR32 processors has arrived – expect the first shipments mid next week as production finishes up the boards.

If you need a larger quantity, please contact us to get a lead time.
