Rabbit-Labs Flipper Zero ESP32-C5 multi-board features CC1101, GPS, and dual-band Wi-Fi 6

Designed by Rabbit-Labs EU, the Flipper Zero ESP32-C5 multi-board is an expansion board for the Flipper Zero built around the ESP32-C5 dual-band Wi-Fi 6 (2.4 GHz and 5 GHz) microcontroller. The board also features a TI CC1101 sub-GHz transceiver, a GPS module, an SD card slot, and a USB-C port for power and programming. Last month, we wrote about the ESP32 Marauder 5G Apex 5 module, another ESP32-C5-based add-on for the Flipper Zero that comes with dual-band Wi-Fi 6, two sub-GHz radios, an NRF24 radio, and a built-in GPS module, which makes it quite bulky, to say the least. Compared to that, Rabbit Labs' multi-board can be considered a stripped-down, simpler alternative, with a more compact design and straightforward setup. ESP32-C5 multi-board specifications: Main module – ESP32-C5-WROOM-1U SoC – Espressif Systems ESP32-C5 CPU Single-core 32-bit RISC-V processor @ up to 240 MHz Low-power RISC-V core @ 40 MHz acting as the

SparkFun OpenScale IoT – An ESP32 board with HX711 ADC for smart scales with WiFi and Bluetooth connectivity

The SparkFun OpenScale - IoT project is a ready-to-use ESP32-based IoT smart scale with open-source hardware and firmware support that makes it easy to read precise weight data from load cells without writing custom code from scratch for basic operation. It handles amplification via the HX711 24-bit ADC, calibration, temperature compensation (using the onboard TMP102 and an optional external DS18B20 probe), and serial output/configuration through a simple text-based menu. It also features Wi-Fi for live data and OTA firmware updates, requiring no dedicated apps—just standard terminal tools and a browser for viewing data. Additionally, there is a Qwiic I²C connector for adding extra sensors or displays. The board operates from 5 V with a typical current consumption of 80 to 100 mA, supports selectable output data rates of 10 or 80 SPS, and includes an adjustable gain for accurate measurements in long-term monitoring setups.

WiFi and Bluetooth LE can now be used simultaneously on Arduino boards with NINA-W102 (ESP32) module

WiFi and Bluetooth LE can now be used simultaneously on Arduino boards with NINA-W102 (ESP32) module

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, impacting the Arduino Nano RP2040 Connect, Arduino MKR WiFi 1010, and Arduino Nano 33 IoT boards. It's a long-running problem since the first Arduino board with NINA-W10 was introduced in 2018, and meant you could use WiFi or Bluetooth LE, but not both simultaneously. The good news is that the issue has finally been fixed, thanks to a new firmware for the module and new WiFi and BLE libraries. More specifically, you'll need the following libraries and firmware: WiFiNINA library version 2.0.0 or later ArduinoBLE library version 2.0.0 or later NINA-W102 firmware version 3.0.1 or later The libraries can easily be updated in the Library Manager in the Arduino IDE, and the firmware needs to be updated with the Firmware Updater Tool in Tools > WiFi101 /
