Voler Systems vs Emcraft Systems: overview
Voler Systems
Voler Systems has operated out of Sunnyvale, California since 1979, making it one of the longest-running independent electronic design consultancies still active in the niche, with a team of roughly 22 engineers today. The firm pairs analog circuit design and FPGA programming with embedded firmware, and its wearable device work leans specifically on ultra-low-power system design, sensor integration, and wireless transmission, the constraints that separate battery-powered wearables from mains-powered embedded products. It also does biomedical sensor and regulatory-support work for medical wearables, an area that draws on both its electronics and firmware disciplines together.
Emcraft Systems
Emcraft Systems is headquartered in Carlsbad, California and builds production-ready system-on-modules around ARM Cortex-M microcontrollers and Cortex-A microprocessors, alongside the Linux and RTOS board support packages that run on them. The company maintains its own BSPs rather than relying solely on a chip vendor's reference package, which gives it long-term update responsibility for the firmware layer under a client's application code. It holds STMicroelectronics partner status, and its board-plus-BSP model suits companies that want a hardware module and a maintained firmware base together instead of sourcing them separately.

Voler Systems vs Emcraft Systems: pros and cons
| Voler Systems | |
|---|---|
| + | 46 years of operating history is unusually long for an independent firmware and electronics design house |
| + | Ultra-low-power design is a stated specialty, not a general capability applied to a battery-powered project after the fact |
| + | FPGA programming alongside firmware covers projects that need custom logic as well as MCU code |
| + | Biomedical sensor and wearable regulatory-support experience spans both hardware and firmware sides of a project |
| - | 22 engineers limits the firm to a small number of concurrent client programs at any time |
| - | Public case study volume is lower than larger firmware consultancies, so verifying specific past projects requires a direct conversation |
| - | No published pricing or minimum engagement figure |
| Emcraft Systems | |
|---|---|
| + | Self-maintained BSPs give long-term update ownership rather than depending on a chip vendor's reference package alone |
| + | STMicroelectronics partner status backs its ARM Cortex-M and Cortex-A module line with direct chip-vendor support |
| + | Combining hardware modules with firmware support removes a sourcing step for companies that would otherwise need two vendors |
| + | Focus on both Linux and RTOS BSPs covers a wider range of real-time requirements than a Linux-only board vendor |
| - | Public founding year and team size figures are thin, and the company's own materials don't publish a founding date directly |
| - | Its business model centers on selling its own hardware modules, which is a narrower fit for a client who has already committed to different silicon |
| - | No published pricing or minimum engagement figure |
