4-inch LF40 square touchscreen display modules are designed for Luckfox Pico Ultra development board

Luckfox IPS Touch Displays LF40 480480 ARK and LF40 720720 ARK

Luckfox LF40-480480-ARK and LF40-720720-ARK are two new 4-inch square touchscreen display modules specially designed for the Luckfox Pico Ultra micro Arm Linux development board. Both displays feature IPS panels with wide viewing angles and capacitive touch input. The display modules connect to the Pico Ultra board via the RGB666 interface ensuring compatibility with the board. Both displays have a brightness of 400cd/m² and an operating temperature range of -20~70°C. The main differences between the two boards are in the resolution, color gamut, and contrast ratio. The LF40-720720-ARK has a resolution of 720×720 pixels with a wider color gamut of 68% NTSC and a 1000:1 contrast ratio. The LF40-480480-ARK on the other hand features a 480×480 pixels display, with an unspecified color gamut and  380:1 contrast ratio.

SparkFun M7E Hecto is a simultaneous RFID Reader with USB-C connectivity and a range of up to 5m

SparkFun M7E Hecto Simultaneous RFID Reader

SparkFun has announced the M7E Hecto, a ‘simultaneous’ RFID reader in a compact form factor and high-performance capabilities. The RFID reader is powered by Jadak’s Hecto module (M7E-HECTO) from the ThingMagic series which offers a wide RF output range from 0 dBm to +27 dBm and reads up to 300 tags/second. SparkFun M7E Hecto builds on the much older M6E Nano RFID reader, adding a USB-C port, increasing the read rate from 150 tags/second, and reducing power consumption. It supports an external antenna (sold separately) which extends the scanning distance up to 16 ft (4.8m) from the 1 to 2 ft (0.3m – 0.6m) range supported by the onboard antenna. It does come with a warning to ensure that personnel are not directly in the radiation beam of the antenna while they are within 21cm of the antenna (to adhere to FCC limits for long-term exposure to RF emissions). The […]

Alfa Networks AHST7394S Wi-Fi HaLow module enables low-power, long-range IoT connectivity up to 1km

Alfa Networks AHST7394S HaLow

Taiwanese wireless equipment manufacturer, Alfa Networks, and US-based Wi-Fi HaLow semiconductor company, Newracom, have collaborated to develop the AHST7394S Wi-Fi HaLow module. The solder-down module is based on Newracom’s NRC7394 SoC, a low-cost and high-efficiency HaLow SoC chipset providing up to 17dbm output power and capable of connecting to a maximum of 8K devices within a single network. The NRC7394 also supports a standalone mode, which enables the execution of a wide range of IoT applications on the embedded ARM Cortex-M3 CPU. While HaLow is more energy-efficient than other Wi-Fi types, low-power operation modes such as legacy, TWT, and WMM-PS can reduce power consumption further. The AHST7394S Wi-Fi HaLow module supports a data rate of up to 15Mbps, over 600 times faster than LoRaWAN while maintaining a good range (over 1km). The second-generation HaLow module is perfect for building long-range, ultra-low-power networks in sub-1 GHz, license-exempt frequency bands. It is a […]
