Āvega Systems designs and prototypes integrated electromechanical systems — unifying mechanical architecture, custom electronics, embedded firmware, and real-time control into working hardware.
Lean team. Tight scope. Fast iteration.
Start a ConversationWe operate at the intersection of mechanical design, electronics, and embedded software — where integration risk is highest and timelines slip.
End-to-end system architecture, requirement definition, actuator sizing, power budgeting, thermal considerations, and integration planning before hardware is committed.
Microcontroller firmware, RTOS integration, motor control, sensor fusion, feedback systems, and real-time control algorithm implementation for high-reliability embedded platforms.
Multilayer PCB design, mixed-signal layout, LiPo-powered systems, robust power stages, and signal integrity considerations for production-ready electronics.
Mechanical fabrication coordination, rapid prototyping, system bring-up, hardware debugging, and validation testing to move from concept to functional prototype.
Proof of capability through delivered hardware — concept to validated prototype.
A portable device was needed to bridge USB MIDI controllers into wireless DAW environments — removing cable dependency without adding software overhead, latency, or single-mode constraints. The design required dual operating modes (BLE wireless and lossless USB passthrough), autonomous LiPo battery management with USB-C charge input, and real-time MIDI protocol translation across USB host and BLE stacks.
Full hardware and firmware stack designed from scratch. Firmware built on ESP-IDF with a custom USB host stack for MIDI parsing and NimBLE for BLE MIDI output, compliant with Apple's BLE MIDI specification. Multi-rail power architecture: BQ24074 LiPo charger, TPS62162 3.3V buck, TLV61047 5V boost for keyboard VBUS, and TPS2116 dual-input power mux for seamless battery/USB-C switching. Hardware USB routing via a TS3USB30E switch isolates the ESP32 entirely during passthrough mode. 7-sheet KiCad schematic and 4-layer PCB layout designed concurrently with firmware development.
End-to-end pipeline validated on bench — USB MIDI keyboard recognised as a standard MIDI port in macOS Audio MIDI Setup, with MIDI data arriving live in FL Studio over BLE. PCB layout complete at 75 × 40mm across 4 layers and 57 components; awaiting fabrication and assembly.
Āvega Systems is a lean engineering studio focused on hard technical delivery across mechanical, electrical, and embedded domains.
We take on tightly scoped, execution-focused engagements where system integration, control architecture, or custom electronics are limiting progress.
We prefer direct technical dialogue, clear constraints, and measurable engineering progress over presentation-heavy consulting. Engagements are tightly scoped, execution-focused, and outcome-driven.
