limor and i can’t purchase teensys from sparkfun anymore, they now decide who can buy, using a secret set of rules. since sparkfun is now the exclusive maker and seller of teensy, and paul and robin apparently have no say, limor and i were informed we’re not allowed to purchase.
instead of being sad about it, we’re doing the obvious thing. we’re making an open-source, teensy-compatible board.
we also just had our second kid a few weeks ago, so the timing is not great. that’s fine. last night, after a cluster breastfeeding session (parents know exactly what that means), limor and i started this project. “freensy” is the working name. it is not the final name. maybe.
features
- open source. anyone can purchase it and or manufacture it
- lower cost: $9.95
core
- rp2350 32-bit cortex m33 dual core
- 150 mhz at 3.3v logic and power
- overclocking:
- 300 mhz often achievable with a small voltage bump, vreg to ~1.20v or 1.25v
- 350 mhz and up requires max safe internal voltage around 1.30v to 1.35v plus some silicon lottery luck
memory and storage
- 520 kb ram + 8 kb otp memory
- 8 mb spi flash for files and circuitpython or micropython storage
- no eeprom
- appears as a usb mass-storage device on your computer
usb and power
- usb host on any two pins
- modern usb-c device
- built-in lipo charging with optional jst connector footprint (or use the vbat pin)
- 600ma peak 3.3v regulator
- 4 layer board with inner ground and 3v planes
io and debug
- stemma qt i2c port for hundreds of sensors, oleds, breakouts, etc
- swd debug footprint on the bottom
indicators
- onboard neopixel
- red status led
software
- open source, non-proprietary bootloader
- supports arduino, micropython, circuitpython, pico sdk, go, rust
mechanical
- color: red
- optional enclosure
- full enclosure design published as free open source so anyone can make or modify it
things we’re thinking about
- should we add an optional footprint for 2 mb or 8 mb psram?
also, we’ll be doing an esp32 p4 version.
nothing says “new baby energy” like starting a new board at 3am and making sure no single company gets to decide who is allowed to build.

snow in brooklyn, ny. gorgeous for a few minutes.
took photos. snow has a way of making space… footsteps, empty benches, the distance between one thought and the next.. ❄️🖤

👶📦 about to bring a whole human into the world and relaunch adabox at the same time. a twofer. i get a baby. you get an adabox. 🚀❤️
next adabox adababy delivery deets and faqs
new products and new humans are getting launched in the next 24 hours. adabox 22 is packed, sealed, and queued for launch, landing right as we welcome our next biological tape out from the fab. before we hit send on the subscriber emails, let’s go over some frequently asked questions, as well as questions you may not have thought to ask (but we’ll answer anyway).
