Makerfabs CM0IQ – An ultra-compact (42x36mm) Raspberry Pi CM0 Lite board

The CM0IQ is an ultra-compact board based on the Raspberry Pi CM0 Lite Compute Module. It measures just 42 × 36 mm and squeezes multiple interfaces into a 15.1 cm² footprint, making it suitable for space-constrained applications such as robotics, IoT devices, and custom hardware integrations. Despite being smaller than a Raspberry Pi Zero 2 W (19.5 cm²), the CM0IQ manages to include a full-sized USB-A port, a Micro HDMI port, and 4-lane MIPI CSI and DSI connectors. To fit everything into this small footprint, the designer also relied on a 1.27 mm 40-pin GPIO header rather than the standard 2.54 mm header. The board also features a USB Type-C for power, a microSD card slot for storage, 5V solder pads for power input, and four M2 mounting threads. Raspberry Pi CM0IQ Specifications: SoM – Raspberry Pi CM0 Lite SoC – Broadcom BCM2710A1 CPU – Quad-core Cortex-A53 processor @ 1.0 GHz […]

SayoDevice O3C 3-Key Hall-effect keypad boasts 8,000Hz polling rate for playing rhythm games

While searching for new products on AliExpress, I came across the SayoDevice OSU O3C, which looks very similar to other macro keyboards such as the 4xMacropad, the LILYGO TTGO T-Encoder, or the T-Keyboard-S3. However, like the TENSTAR T-Display, it sold over 10,000 pieces on Aliexpress. This warranted an investigation, and I found that it is actually a Hall-effect keypad mainly designed for rhythm and single-input games such as osu! and Geometry Dash. The keypad features OUTEMU magnetic Hall-effect switches with rapid trigger support and a customizable actuation point as low as 0.05 mm, for extremely fast and precise keystrokes. The keyboard connects to a PC via a USB 2.0 cable and supports an 8,000 Hz polling rate for low input latency. The device includes a 0.96-inch IPS color display that can show key travel information, key press counts, or custom images and text, and the first line of the screen […]

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

Arduino Nano RP2040 Connect WiFi and Bluetooth

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 / […]

Upgraded FGH200M Wi-Fi HaLow module features Morse Micro MM8108 SoC, handles up to 8,191 IoT devices

Introduced at MWC 2026, Quectel FGH200M Wi-Fi HaLow module, based on Morse Micro MM8108 SoC, is an upgraded version of the previous MM6108-based FGH100M module designed for long-range, low-power IoT connectivity. It operates in the sub-1-GHz band (850–950 MHz), with a range of up to 1 km, and is designed for applications such as smart homes, industrial automation, smart agriculture, smart cities, building automation, warehouses, campuses, and large-area IoT networks. The module operates on 1/2/4/8 MHz channels, with a maximum physical data rate of 43.3 Mbps and a transmit power of 26 dBm, allowing a single access point to theoretically connect up to 8,191 IoT devices. It connects to the host through USB 2.0, SDIO 2.0, or SPI interfaces. The ultra-compact (11.0 × 10.0 × 2.0 mm) LGA package operates in industrial environments with a temperature range of –40°C to +85°C. Quectel FGH200M Specifications: SoC – Morse Micro MM8108 32-bit […]

Silex SX-SDMAX6E tri-band Wi-Fi 6E + Bluetooth LE module features NXP IW623 SoC, comes in M.2 or LGA package

Silex SX SDMAX6E tri band Wi Fi 6E + Bluetooth LE module LGA(Right) M.2(Left)

Back in August last year, we wrote about NXP’s IW623 tri-band (2.4GHz, 5GHz, 6GHz) Wi-Fi 6E and Bluetooth LE Audio SoC, but at the time, there was no ready-to-use module based on it. Now, NXP has partnered with Silex Technology to launch the SX-SDMAX6E module, available in a surface-mount LGA package or an M.2 2230 Key-E card. The module supports Bluetooth 5.x connectivity via UART and Wi-Fi via SDIO. It operates from a 3.3V supply with 1.8V support on the LGA version. It has an industrial operating temperature range of -40°C to +85°C and is designed for both high-throughput applications, such as video streaming, and low-power, battery-operated devices in harsh environments. It also supports various antenna options, fast roaming, and long-term lifecycle backing through Silex and NXP. Silex SX-SDMAX6E specifications: Wireless chipset – NXP IW623 tri-band SoC Connectivity Wi-Fi Tri-band Wi-Fi 6E (2.4 GHz, 5 GHz, 6 GHz) IEEE 802.11a/b/g/n/ac/ax […]

Add a tiny desktop monitor to your PC with the ESP32 Desktop Monitor project

While searching AliExpress for new products, I found the TENSTAR T-Display ESP32-D0WD with a 1.14-inch IPS color IPS LCD and 16MB of QSPI flash that’s used by some as a tiny secondary mirrored monitor for their PC. The board appears to be a low-cost alternative to the original LilyGo T-Display, and also integrates a USB-to-TTL converter (CH9102F), a battery charging circuit, a toggle switch, and two user-programmable buttons, which makes it suitable for projects like the NerdMiner and small-scale dashboards for home automation. The hardware does not seem special, yet they sold over 10,000 pieces of the board. After looking into it, the ESP32 Desktop Monitor project is probably the “culprit” for the high sales number, as it transforms the board into a regular monitor, albeit with a tiny 1.14-inch LCD. More on that after the specifications. TENSTAR T-Display Specifications: SoC – Espressif Systems ESP32-D0WDQ6-V3 MCU cores – Dual-core Xtensa LX6 32-bit […]
