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.

M5Stamp C6LoRa tiny (18×15×2.3 mm) SMD module pairs ESP32-C6 with SX1262 LoRa chip

The M5Stamp C6LoRa is a compact LoRa SMD module that combines the ESP32-C6 Wi-Fi 6, Bluetooth LE, and 802.15.4 microcontroller with the SX1262 LoRa transceiver for both high-speed and long-distance communication. The module targets applications such as smart agriculture, remote meter reading, industrial monitoring, and outdoor long-range wireless control systems. The module measures 18 × 15 × 2.3 mm, making it suitable for space-constrained systems and compact embedded designs. M5Stack has also added an SGM13005L4 low-noise amplifier (LNA) to improve reception performance, along with a PI4IOE5V6408 I/O expander that manages the LoRa control signals without using too many of the ESP32-C6’s GPIO pins. M5Stamp C6LoRa specifications: SoC – Espressif Systems ESP32-C6 CPU Single-core 32-bit RISC-V clocked up to 160 MHz Low-power RISC-V core @ up to 20 MHz Memory/Storage – 512KB SRAM, 320KB ROM Wireless - WiFi 6, BLE 5.3, 802.15.4 (See wireless section) Storage – 16 MB external NOR flash

What hardware do y'all use for your BLE → MQTT bridge?

When it comes to #IoT protocols there are two main options: #BLE vs #openthread.

While openthread is mainly focused in industrial applications, BLE has massive commercial appeal. Because of this BLE is a rapidly progressing tech comparatively, and superior in terms of speed and reliability.

While BLE goes to 2 Mbit/s, openthread delivers 250kbps. Considering IoT applications are #lowpower nodes, this high throughput helps quick transmissions and save power.

On the other hand, openthread boasts native #ipv6 access, only requiring a "border router".

And as it needs a openthread border router device anyway - IMO we might as well write and put a relay app in it, taking away openthread's advantage...
