Espressif ESP32-C61-MINI-1/1U Wi-Fi 6 and BLE IoT module launched for about $2

Back in 2024, Espressif Systems introduced the ESP32-C61 2.4 GHz WiFi 6 and Bluetooth LE (BLE) SoC as a low-cost variant of the ESP32-C6 without an 802.15.4 radio, a single RISC-V core, and lower-capacity SRAM (320KB vs 512KB). We had first seen the ESP32-C61 in the Wireless Tag ESP32P4C61 board introduced last June in a Kickstarter campaign last June, but Espressif has now started to sell samples of the ESP32-C61-MINI-1 and ESP32-C61-MINI-1U on AliExpress for $10.7 for a pack of 5 pieces, or around $2 per module. ESP32-C61-MINI-1/1U Module specifications: SoC – ESP32-C61 CPU core – Single-core 32-bit RISC-V microprocessor up to 160 MHz Memory 320KB SRAM Up to 8 MB PSRAM Storage 256KB ROM Up to 8 MB Quad SPI flash Wireless 2.4 GHz WiFi 1T1R Frequency: 2412 ~ 2484 MHz IEEE 802.11ax-compliant 20 MHz-only non-AP mode MCS0 ~ MCS9 Uplink and downlink OFDMA Downlink MU-MIMO Target wake time […]

Arduino launches Modulino Hub and Extender modules to support up to 64 I2C devices, 30-meter range

Arduino Modulino Hub Extender I2C modules

Arduino has just introduced three new Modulino modules: the Modulino Hub to support up to eight I2C devices (64 devices with 8 Hubs), the Modulino Extender to extend the I2C range to up to 30 meters, and the Modulino Motors to control two DC motors or a single stepper motor with precision. I’ll focus on the I2C modules in this post, as I find the Modulino Extender module particularly interesting, since I always considered I2C to be a short-range communication protocol, and never thought of using it for (relatively) long-range wired communication. Modulino Hub While the I2C protocol supports up to 127 devices in theory, address conflicts can become an issue in complex builds where multiple sensors or actuators share the same default address. The Modulino Hub aims to solve that, and multiple Hubs can be daisy-chained, each with its own address, to support up to 64 devices. Modulino Hub specifications: […]

Morse Micro MM8108-M20 high-power Wi-Fi HaLow module delivers up to 28.5 dBm Tx output power

Morse Micro MM8108-M20 is a high-power Wi-Fi HaLow module based on the MM8108 SoC and a high-power amplifier delivering up to 28.5 dBm transmit output power, alongside a surface acoustic wave (SAW) filter tuned for the 902-928 MHz band of the North American market. Other MM8108 modules, such as the Quectel FGH200M Wi-Fi HaLow module, are limited to 26 dBm Tx power, but US and Canada regulations enable higher power transmissions, and by extension longer range. The obvious downside of the MM8108-M20 is that it might be outright illegal or may require a special license in other countries.
