Sensy32 Board is an ESP32-S3 sensor platform with up to six sensors for environmental monitoring in IoT applications

The Sensy32 Board is a compact sensor platform powered by Espressif’s flagship ESP32-S3 WiFi and Bluetooth microcontroller. The development board brings different monitoring devices together on the same PCB for easier integration into IoT ecosystems. It is a multipurpose device with several sensors bundled to measure and monitor ultraviolet light intensity, altitude, pressure, orientation, humidity, temperature, motion, and human presence. It includes a 9-degree-of-freedom inertial measurement unit (IMU) for 3D space orientation, while the built-in MEMS microphone can be used for audio input in voice detection and noise measurement applications. The onboard ESP32-S3 microcontroller powers the array of features and also offers Wi-Fi and Bluetooth Low Energy connectivity. The Sensy32 ESP32-S3 sensor platform also integrates an LCD screen for immediate feedback and real-time monitoring. We have covered other ESP32-based environment sensors such as the Qsen-07 multi-sensor board, AirGradient ONE, MoreSense MS-06, and Studio LUFF’s Air Quality Sensor. Sensy32 specifications: MCU […]

SenseCAP Indicator – An ESP32-S3 and RP2040-based Meshtastic LoRa device with a 4-inch touchscreen display

The SenseCAP Indicator is a 4-inch capacitive touchscreen device designed for IoT connectivity and Meshtastic applications powered by Espressif Systems ESP32-S3 and Raspberry Pi RP2040 microcontrollers. It supports Wi-Fi (802.11b/g/n) and Bluetooth 5.0 LE connectivity, as well as LoRa using the Semtech SX1262 chip. The device also provides Grove connectors for expansion and a microSD slot supporting up to 32GB. Preloaded with Meshtastic firmware, the SenseCap Indicator is ready to function as a Meshtastic desktop or car node and can be reconfigured into a LoRaWAN Single-Channel Gateway. It features a 3.95-inch RGB touchscreen with 480×480 resolution, which is larger than most other Meshtastic solutions we’ve covered. Previously, we reviewed the SenseCAP Indicator D1Pro, which shares many features with the SenseCAP Indicator. However, the D1Pro integrates tVOC and CO2 sensors, along with an external Grove AHT20 TH sensor for precise temperature and humidity measurements. With real-time air quality monitoring from the […]

CapibaraZero firmware enables low-cost Flipper Zero alternatives based on ESP32-S3 hardware

CapibaraZero open-source firmware aims to offer a low-cost alternative to Flipper Zero for ESP32-S3-based hardware platforms and soon other gizmos with ESP32 wireless microcontrollers, notably the LilyGO T-Embed CC1101, similar to the original T-Embed with ESP32-S3 WiSoC, but also featuring a Texas Instruments CC1101 Sub-GHz microcontroller and an NXP PN532 NFC/RFID module. The Flipper Zero is a popular portable multi-tool for pentesters and hardware hackers based on STMicro STM32WB55 Bluetooth 5 LE & 802.15.4 wireless microcontroller and a TI CC1101 Sub-Ghz MCU that got involved in controversies such as a ban proposal in Canada last year due to its (dubious) potential use for car theft. Since then we’ve seen several alternatives such as Monstatek M1 (that’s yet to be delivered to backers…) and HackBat open-source hardware with Raspberry Pi RP2040,  ESP8266 WiFi module, and the CC1101 RF transceiver. The CapibaraZero firmware offers another way to create your own cheap Flipper […]

ESP32 Rainbow is an open-source, ESP32-S3-powered ZX Spectrum single board computer (Crowdfunding)

Retrocomputing enthusiasts will be delighted to learn that a new ZX Spectrum replica is on the market: the ESP32 Rainbow. The single board computer swaps the Zilog Z80 for an ESP32-S3 microcontroller chip running an emulator, bringing the classic 80s computer back to life with a modern twist. It features a built-in color display, a microSD card slot for storage, a built-in touch keyboard in the ZX Spectrum style, and a USB Type-C port for power and data. The keyboard was recreated using full-color UV printing and is the most true-to-life component of the ESP32-S3-based ZX Spectrum single board computer. The touch keys won’t likely offer the best typing experience but that is reminiscent of the original ZX Spectrum. A lovely cherry on top is that the onboard USB-C port supports HID and the device can be used as a keyboard on another computer. The ZX Spectrum is one of […]
