M5Stack Capsule Kit v1.1- A Battery-powered ESP32-S3 IoT controller with IMU sensor, MEMS microphone, and IR transmitter

M5Stack Capsule v1.1 is a Stamp-S3A-based IoT controller with a microSD card slot, several sensors (6-axis IMU, microphone),  an IR transmitter, a built-in 250 mAh battery, a few buttons, a buzzer, an RTC, and expansion capabilities through GPIO headers and a Grove connector. It's an upgrade to the earlier Capsule based on the Stamp-S3 module. The new version still features an ESP32-S3 WiFi and Bluetooth microcontroller, 8MB flash, a USB-C port, and a few GPIOs, but benefits from the Stamp-S3A improvements, including an optimized antenna design and lower power consumption. We never had a look at the Capsule before, so let's do it now. M5Stack Capsule v1.1 specifications: M5Stack Stamp-S3A module WiSoC – Espressif Systems ESP32-S3FN8 CPU Dual-core 32-bit Xtensa LX7 microcontroller with AI vector instructions up to 240MHz RISC-V ULP co-processor Memory – 512KB SRAM Storage – 8MB flash Wireless – 2.4GHz WiFi 4 (802.11b/g/n), Bluetooth 5.0 LE +

CardputerZero pocket computer combines the brains of a Raspberry Pi Zero 2W with a tiny display, keyboard, and battery

The M5Stack CardputerZero is a tiny, portable computer that’s about the size of a small stack of business cards. But despite its compact size, it’s a full-fledged PC with a display, keyboard, and support for Linux-based software.

M5Stack has been selling similar devices under the Cardputer brand for a few years, but up until now they’ve featured ESP32 microprocessors and far too little memory […]

Кто смотрел выпуск @regex где мы обсуждали #Meshtastic, видели мой #M5Stack Cardputer Adv и я вроде рассказывал о приключениях, связанных с отсутствием для него официального билда Meshtastic, и о загрузчике M5Launcher.

Так вот теперь официальный билд не только есть (в альфе), но M5Stack даже выпустили специальный комплект, который я "случайно" собрал по частям: это точно такой же Cardputer Adv, только с зелёной половиной корпуса (смотрится, ИМХО, ужасно), и шляпка на базе радиочипа SX1262 с антенной под 868 МГц.

Обновлённая прошивка вполне себе втыкается через M5Launcher, например, вот так:
* снять бэкап настроек в приложении Meshtastic
* выбрать желаемый релиз (скорее всего последнюю альфу) на https://github.com/meshtastic/firmware/releases/
* скачать оттуда архив с названием вида firmware-esp32s3-*.zip (по модели чипсета)
* достать там бинарник вида firmware-m5stack-cardputer-adv-*.bin (без factory)
* [переименовать и] положить на microSD-карточку устройства
* прошить через M5Launcher
* …
* PROFIT

PCMFlow722 library enables two-way real-time HD voice over ESP-NOW with G.722 audio codec

https://fed.brid.gy/r/https://www.cnx-software.com/2026/05/30/pcmflow722-library-enables-two-way-real-time-hd-voice-over-esp-now-with-g-722-audio-codec/

PCMFlow722 library enables two-way real-time HD voice over ESP-NOW with G.722 audio codec

Tanaka Masayuki's PCMFlow722 library enables (half-duplex) two-way real-time HD voice over ESP-NOW on ESP32 boards with a speaker and a microphone, effectively transforming them into walkie-talkies. The library implements a G.722 wideband codec add-on for PCMFlow lightweight audio decode and PCM flow library for Arduino, which already supports uncompressed PCM, MP3, and FLAC audio codecs. PCM and FLAC take too much bandwidth over ESP-NOW, and MP3 is not suitable for real-time audio, so the legacy G.722 audio codec was selected instead. The keyword here is "HD voice," since two-way audio over ESP-NOW was previously implemented in projects such as Atomic14's esp32-walkie-talkie (5 years ago) and, more recently, the well-documented Adafruit ESP-NOW Walkie-Talkie project, but these typically rely on lower-quality G.711 audio or compressed audio. The PCMFlowG722 library and G.722 codec enable HD voice with "7 kHz audio at 16 kHz sampling using the same 64 kbps wire budget as G.711
