Volt

Embedded/IoT

Firmware that runs reliably on hardware that can't be easily patched.

Embedded systems engineer who builds firmware for any MCU platform including ESP32, STM32, and Nordic nRF. Writes device drivers for I2C and SPI sensors and protocol handlers for BLE, MQTT, and Modbus. Creates OTA update systems with dual-partition A/B schemes, firmware signature verification, and rollback. Audits power budgets including sleep modes, wake sources, and radio duty cycles for battery life targets.

Everything Volt can do in your project

VoltEmbedded

/volt-firmware

Scaffolds a complete embedded firmware project for a target MCU: RTOS task structure with stack size planning, peripheral initialization sequences, power management state machine, communication stack (BLE, MQTT, or serial protocol), OTA update client, and CI build configuration. Available for ESP-IDF, STM32 HAL, Zephyr, and Arduino frameworks.

When starting a new embedded or IoT device project…

VoltEmbedded

/volt-driver

Writes a device driver or protocol handler with a clean HAL abstraction layer: I2C and SPI sensor drivers with interrupt-driven I/O, BLE GATT service implementations, MQTT client with reconnection logic, or Modbus RTU handlers. Designed to be unit-testable and portable across hardware revisions.

When integrating a new sensor, peripheral, or comm…

VoltEmbedded

/volt-ota

Builds a complete OTA firmware update system: dual-partition A/B storage with partition manager configuration, firmware image signature verification to prevent unauthorized updates, download with resume capability on connection loss, atomic partition swap, and automatic rollback if the new firmware fails to boot successfully.

When devices are deployed in the field and need re…

VoltEmbedded

/volt-recon

Firmware reconnaissance: inventories the MCU and full peripheral set, maps RTOS tasks with their stack usage and priorities, documents communication protocols and data flows, assesses OTA system readiness, audits power management implementation, and produces code quality risk flags for inherited firmware.

When taking over a firmware project without docume…

VoltEmbedded

/volt-power

Analyzes the firmware power budget: maps all sleep modes and their wake sources, audits power state machine transitions for missing low-power states, measures radio duty cycles for BLE and WiFi including advertising intervals and connection parameters, and estimates battery life under different usage pattern scenarios.

When a battery-powered device is not meeting its b…
