  3. Show HN: ESP32-S3 probe – a UART "flight recorder" with auto frame decoder (github.com)

    Hi HN, I built a small UART analyzer using an ESP32-S3 as a cheap probe. It taps the target’s TX at 921600 baud and streams raw bytes to the PC over USB CDC. To make it robust and easy to resync, the S3 wraps data into…

  4. Show HN: LinkScope – Real-Time UART Analyzer Using ESP32-S3 and PC GUI (github.com)

    Hi HN, I built a real-time UART analyzer using an ESP32-S3 and a Windows GUI. It captures high-speed UART data and shows live statistics and visualization on PC. Main features: - Up to 921600 baud capture - Real-time…

  5. Show HN: BPU – Reliable ESP32 Serial Streaming with Cobs and CRC (github.com)

    Hi HN, I’d like to share BPU, a high-speed serial streaming engine I built using ESP32 devices. BPU is a small experimental project that demonstrates a reliable data pipeline: ESP32-WROOM → ESP32-S3 → PC Data is…

  6. Show HN: Handling UART backpressure on ESP32 without blocking producers (github.com)

    While working with ESP32, I kept running into the same failure mode: UART / BLE output occasionally falls behind, and simple queues either grow unbounded or force producers to block. I built a small embedded scheduling…
