esp-hal is a bare-metal (no_std) hardware abstraction layer written in Rust for Espressif ESP32-family microcontrollers, covering ESP32, C, H, P, and S series chips. It provides embedded-hal-compatible drivers and supporting crates for peripherals, low-power cores, storage, and RTOS functionality without an underlying OS.

Use cases

• write Rust firmware for ESP32 microcontrollers
• build no_std embedded applications on ESP32-C3
• drive ESP32-S3 peripherals with embedded-hal traits
• program the low-power RISC-V core on ESP32-C6
• develop bare-metal IoT devices without an RTOS
• flash and manage storage on ESP32 chips from Rust

When to choose

• you want to write Rust firmware for any ESP32-family chip without an OS
• you need a no_std, embedded-hal-compatible HAL with active Espressif support
• you are targeting low-power cores or a wide range of ESP32 variants from one codebase

When to avoid

• you need a full ESP-IDF environment with FreeRTOS and standard library (use esp-idf-svc instead)
• you are targeting non-Espressif microcontrollers
• you need guaranteed stability of every advanced peripheral feature, as some crates are still maturing
