SparkFun's Latest MicroMod Processor Brings a Teensy 4.0 to the Ecosystem — with 8MB of Flash, Too

Built in partnership with PJRC, the SparkFun MicroMod Teensy Processor turns any MicroMod carrier board into an upgraded Teensy 4.0.

SparkFun has announced a new entry to its MicroMod family of modular microprocessors, partnering with PJRC to bring the popular Teensy to the lineup.

Launched late last year, SparkFun's MicroMod ecosystem is designed to do away with the issue of a new development board making your old projects obsolete. The MicroMod family is split in two: One half covers carrier boards on which you build your projects; the other half processor boards. If a new processor comes out, or you find that your old one is too underpowered for the job, you just pop the old module out and put a new one in its place.

The MicroMod ecosystem has been growing steadily since its unveiling, and now it has a new processor module to its name — and this one turns any MicroMod carrier board into a Teensy.

"Today SparkFun is releasing MicroMod Teensy - a product of collaboration between PJRC and SparkFun," PJRC's Paul Stoffregen announced earlier today. "MicroMod Teensy has essentially the specs of Teensy 4.0 (eg, 600MHz [Arm Cortex-]M7) but with larger flash memory. It will be fully supported by the Teensyduino add-on to the Arduino IDE."

The full specifications include an NXP iMXRT1062 system-on-chip, 8MB of flash memory, 1024kB of RAM, two UART ports, two I2C buses, two SPI ports, CAN bus, 12 general-purpose input/output (GPIO) pins with two dedicated analog and two pulse-width modulation (PWM) pins, digital audio capabilities, and USB Host support — all on a tiny board which uses an M.2 form factor.

The module is compatible with all MicroMod carrier boards — which is, of course, the entire point of the MicroMod ecosystem in the first place - and is now available on the SparkFun store at $19.95 before volume discounts. More information is available in SparkFun's hookup guide.
