Top expert inInternet of Things (IoT) Development and Prototyping
Limor Fried is the founder and chief engineer behind Adafruit, a woman-owned maker-focused hardware company she started after graduating MIT and has grown into a 100+ person NYC manufacturer and learning platform. With 18 years leading product design, open-source hardware and embedded software, she combines low-level firmware expertise—contributing heavily to CircuitPython, UF2/tinyuf2 bootloaders, display and sensor Arduino libraries—and hands-on selection and testing of every product sold. Her work spans bootloaders, graphics drivers, sensor drivers, NeoPixel and RTC libraries, and Raspberry Pi integration, reflecting deep competence in MCU platforms from SAMD to ESP32 and RP2040. A visible public technologist—first female engineer on WIRED’s cover and a White House Champion of Change—she pairs community education with pragmatic engineering and manufacturing at scale. Not obvious from headlines: she still commits code to core embedded toolchains and graphics libraries used by hobbyists and professionals worldwide.

Mar 2012 - Jul 2022
An interrupt-based GPS Arduino library for no-parsing-required use
Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:2 releases, 7 reviews, 61 commits in 10 years 5 months
Contributions summary:Limor contributed to an Arduino library for GPS modules. Their work focused on implementing parsing functionality for NMEA sentences, specifically GGA and RMC. They added the capability to extract relevant data like time, date, latitude, longitude, speed, and altitude. Additionally, they created examples that demonstrate how to use the library and access the parsed GPS data.

Mar 2010 - May 2022
A fork of Jeelab's fantastic RTC Arduino library
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:8 reviews, 37 commits, 19 PRs in 12 years 4 months
Contributions summary:Limor primarily contributed to the RTClib library, focusing on adding and improving support for various Real-Time Clock (RTC) chips, including the DS1307, PCF8523, and DS3231. Their work involved adapting the library for different platforms, resolving compilation issues, and fixing bugs related to timekeeping calculations and I2C communication. The user also added example code and features such as day of the week printing, demonstrating hands-on experience with embedded system RTCs.
