Core1121 sub-GHz, S-Band, and 2.4GHz LoRa module features through holes and castellated edges

Core1121 LF HF Dual Band LoRa Module

The Waveshare Core1121 is a compact, multi-band LoRa module based on the Semtech LR1121 transceiver with support for Sub-GHz (150–960MHz), S-band (1.9–2.1GHz), and 2.4GHz ISM bands, and exposing GPIOs through both through and castellated holes. Key features include support for LoRa, (G)FSK, and LR-FHSS modulation schemes, AES-128 encryption, and compatibility with the SX126X/SX127X series for easy migration. We just noted Seeed Studio’s Wio-LR1121 last week with a very similar, yet more compact design with only castellated holes, and before that, the LR1121 was used in the MuRata Type-2GT module and a LILYGO module as an option for the T-Eth Elite board. Core1121 specifications: RF Transceiver – Semtech LR1121 Frequency bands Sub-GHz (150MHz ~ 960MHz), Different varieties for Europe, North America, Oceania, Asia S-band (1.9GHz ~ 2.1GHz) 2.4GHz ISM frequency bands Output Power Up to 22dBm @ 868/915 MHz (Sub-GHz) Up to 13dBm max @ 2.4GHz Receiver Sensitivity -127dBm @ Sub-GHz, SF7, CR4/5, […]

$14 development board features GUITION ESP32-P4 + ESP32-C6 module

JC ESP32P4 M3 DEV ESP32 P4 evolution board

While searching Aliexpress for new products, I found out about the JC-ESP32P4-M3-DEV from the Maker Go AliExpress store, another ESP32-P4 development board with features very similar to the  ESP32-P4-Function-EV-Board or the Wireless Tag WT99P4C5-S1 board, but built around the GUITION JC-ESP32P4-M3-C6 module, which combines ESP32-P4 and ESP32-C6 into a single package instead of having separate chips or modules on most other designs. Features include 32MB of PSRAM and 16MB of flash on the GUITION module, a microSD card slot for storage, a built-in microphone, speaker output via the ES8311 audio codec, and an audio amplifier. The board also offers a 10/100Mbps Ethernet RJ45 port, an RS-485 terminal block, a GPIO header, and expansion connectors for both the ESP32-P4 and ESP32-C6 chips. Additionally, there are three USB ports: two USB-C and one USB-A for power, data, and debugging, along with a few buttons and LEDs. JC-ESP32P4-M3-DEV evolution board specifications: Core module […]

Wio-LR1121 tiny LoRa module supports for sub-GHz, S-Band, and 2.4GHz frequency bands

Wio LR1121

Seeed Studio Wio-LR1121 is a tiny, multi-band LoRa module based on LR1121 RF transceiver, a low-cost version of LR1120 without GNSS or Wi-Fi scanning capabilities, that supports sub-GHz, S-Band (1.9-2.1GHz), and 2.4GHz frequency bands. We had previously seen the LR1121 used in the MuRata Type-2GT module and a LILYGO module as an option for the T-Eth Elite board. The Wio-LR1121 offers another option that’s easy to solder, thanks to castellated holes and pads. Wio-LR1121 specifications: RF Transceiver – Semtech LR1121 Frequency bands – 863 to 928MHz and 2.4 to 2.5GHz frequencies; Note: The LR1121 also supports S-Band at 2.1 to 2.3 GHz, but it’s not mentioned in the specifications of the module, and  only briefly in the title and description Output Power Up to 20.4dBm @ 868/915 MHz Up to 11dBm max @ 2.4GHz Receiver Sensitivity RxBoost ON： -126dBm @ SubG,BW=125KHz, SF = 7 -140dBm @ SubG, BW=125KHz, SF = […]

Raspberry Pi Radio Module 2 (RM2) is officially available for $4

Raspberry Pi Radio Module 2

Raspberry Pi has just announced the general availability of the Radio Module 2 (RM2) wireless module with WiFi 4 and Bluetooth LE connectivity for $4. The Raspberry Pi RM2 wireless module was already available to some select partners, which explains why the Raspberry Pi RM2 was found in the Pimoroni Pico Plus 2 W and SparkFun Thing Plus – RP2350 since the end of last year. The latest announcement just means it’s available to anybody, and documentation like the datasheet has been released publicly. Raspberry Pi Radio Module 2 (RM2) specifications: Chipset – Infineon CYW43439 combo chip 2.4 GHz Wi-Fi 4 (802.11b/g/n) up to 96 Mbps PHY rate, support for 20 MHz channels Bluetooth 5.2 Classic and LE SISO (Single Input, Single Output) configuration (1×1) Castellated edge pads 3x GPIO gSPI (general SPI) interface to Raspberry Pi microcontroller using PIO Power On/Reset pins Antenna – Shared 2.4 GHz antenna for […]

Airgain introduces plug-and-play NimbeLink Skywire Cat 1bis embedded modem for industrial IoT applications

Airgain NimbeLink Skywire Cat 1bis plug and play module

Airgain has recently launched the pre-certified NimbeLink Skywire Cat 1bis Embedded Modem, which it claims is the “industry’s first plug-and-play Cat 1bis modem for end-application use in industrial IoT”. We’ve already seen several Cat 1bis modules for industrial IoT applications such as the u-blox SARA-R10001DE and Cavli C17QS, among others. What Airgain highlights here is its module’s plug-and-play ability through the Skywire interface (two headers), while other modules typically need to be soldered on the PCB. Airgain NimbeLink Skywire Cat 1bis modem specifications: Based on Quectel EG916Q-GL module Cellular 4G LTE Bands LTE-FDD: B1, B2, B3, B4, B5, B7, B8, B12, B13, B18, B19, B20, B25, B26, B28, B66 LTE-TDD: B34, B38, B39, B40, B41 SIM card Micro (3FF) SIM slot Verizon MFF2 SIM Data rates – Up to 10 Mbps downlink and 5 Mbps uplink Variants North America (TC1bisNAG model) – AT&T, Bell, Rogers, Telus, Verizon networks Worldwide (QC1bisWWG […]

ESP32-C61-DevKitC-1 development board features ESP32-C61 low-cost WiFi 6 and Bluetooth LE 5.0 SoC

ESP32-C61-DevKitC-1 development board

The ESP32-C61-DevKitC-1 is a development board based on the ESP32-C61 low-cost WiFi 6 and Bluetooth LE 5.0 SoC that was first unveiled in January 2024, and has just entered mass production this month (June 2025). The board is offered with two USB-C ports, two buttons, an RGB LED, and GPIO headers. In my 2024 year in review report, I noted that Espressif would likely launch the ESP32-C5 dual-band WiFi 6 SoC in 2025, but I completely forgot about the ESP32-C61, which is basically a cost-down version of the ESP32-C6. The ESP32-C61-DevKitC-1 development board and ESP32-C61-WROOM-1 module are now available, so let’s have a closer look. ESP32-C61-DevKitC-1 specifications: Wireless module – ESP32-C61-WROOM-1 SoC – ESP32-C61HR2 CPU – Single 32-bit RISC-V core clocked up to 120MHz Memory – 320KB SRAM, 2MB PSRAM Storage –  256KB ROM Wireless – WiFi 6 and Bluetooth LE 5.0 Storage – 8MB QSPI flash Antenna – PCB […]
