About JCL Eletronic LTDA
JCL Eletronic is a Brazilian engineering company that builds complete products — not just code. We combine embedded hardware design, firmware development, and full-stack software into a single team, so clients get one partner instead of juggling separate vendors for electronics, firmware, and apps.
Our team is backed by 23+ years of experience in automotive electronics manufacturing, giving us hands-on expertise in PCB design, SMD production at scale, CAN bus/OBD-II systems, and embedded firmware (ESP32, PIC) — capabilities most software-only outsourcing firms simply don't have.
What we do:
- Embedded hardware design & prototyping (schematic, PCB, BOM)
- Firmware development (ESP32, PIC, real-time systems, sensor fusion, BLE, CAN bus)
- Full-stack web & mobile development (React, Node.js, Supabase, PWAs)
- Product engineering from concept to production-ready manufacturing
Recent projects include a wearable motion-tracking device (ESP32-C3 + IMU + BLE 5.0) for a sports-tech client, a CAN bus vehicle diagnostics tool, and embedded control systems for a medical device manufacturer — work that required both hardware reliability and clean software delivery under real production constraints.
Based in São Paulo state, Brazil, we operate in near real-time overlap with US business hours, enabling daily stand-ups and fast iteration without the communication lag typical of offshore teams in Asia. English-language communication and USD invoicing available.
If your product needs both circuits and code, we're the team that builds both — end to end.
