4-inch square HDMI displays with USB touchscreen sell for $33 and up

4-inch HDMI touchscreen displays raspberry pi

We’ve already seen some small HDMI displays, mostly useful for SBCs like Raspberry Pi boards, including a 7-inch monitor with a stand, a 7-inch HDMI touchscreen display, and a 7.9-inch ultrawide HDMI display. Today, I’ve come across another form factor with two 4-inch square HDMI touchscreen displays with 720×720 resolution: the VIEWE model appears to be new and is the cheaper of the two at about $33, while the Waveshare “4inch HDMI LCD (C)” has been around for a couple of years and offers extra features such as a 3.5 mm audio jack and speakers support, and mounting for Raspberry Pi 3/4/5 single board computers with adapters. VIEWE 4-inch square HDMI touchscreen display VIEWE 4-inch HDMI display (UEDX72720040-HMD-RB-A) specifications: Display 4-inch square HDMI TFT display with 720×720 resolution ST7703 display driver Brightness – 300 cd/㎡ Active area – 71.93 x 71.93 mm Touchscreen – 5-point capacitive touch screen via USB-C […]

Chipsee PPC-CM5-156 Review – Part 2: A Raspberry Pi CM5 fanless Panel PC tested with Raspberry Pi OS

We’ve already had a look at the hardware of Chipsee’s 15.6-inch industrial touch panel PC in the first part of the review, before booting it to Raspberry Pi OS. I’ve now had time to test most features of the PPC-CM5-156 panel PC running Raspberry Pi OS, so I’ll report my experience testing performance and most ports of the Raspberry Pi CM5-based system in the second part of the review.

PPC-CM5-156 panel PC system info and sbc-bench.sh benchmark

Let’s check the features of the PPC-CM5-156 panel PC using the inxi utility:

Infineon PSoC 4100T Plus multi-sense Arm Cortex-M0+ MCU supports ML-based liquid level sensing, wake-on-touch with 8µA deep sleep mode

Infineon PSoC 4100T Plus is a new low-power Arm Cortex-M0+ MCU designed for battery-powered or low-power embedded systems that require advanced capacitive touch and proximity sensing. The microcontroller comes with 128 KB of flash, 32 KB of SRAM, and an 8 KB ROM. One of the most interesting features of this MCU is Infineon’s fifth-generation CapSense MSCLP technology, which enables high-resolution, low-power capacitive sensing even in deep sleep mode (as low as 8 µA). Its capacitive sensing uses both self and mutual capacitance methods, supported by analog front-end filtering, sigma-delta modulation, and digital filtering techniques, delivering a signal-to-noise ratio greater than 5:1 for accurate detection. The MCU supports gesture detection, human-machine interfaces (HMI), and smart sensing applications, making it ideal for wearables, consumer devices, and IoT systems. Additional features include a 12-bit 1-MSps SAR ADC, six TCPWM blocks, smart I/O with programmable logic functions, multiple UART/I2C/SPI interfaces, and up to […]

Infineon PSoC 4000T multi-sense low-power MCU features capacitive, inductive, hover, and non-contact liquid sensing

Infineon 4000T multi sense low power MCU

Infineon Technologies has introduced the PSoC 4000T Multi-Sense low-power MCU, along with the upcoming PSoC 4100T Plus which will feature higher memory and more I/Os. These MCUs integrate fifth-generation CAPSENSE technology along with Multi-Sense capabilities, including proprietary inductive sensing, and non-contact liquid sensing solutions. This combination makes it easy to develop advanced HMI applications, such as touch-over-metal, hover touch, and accurate liquid-level detection. The MCU also supports SmartSense auto-tuning which eliminates manual calibration. It supports Always-On sensing with 10x lower power consumption and 10x higher SNR than previous generations. Additionally, the MCU enables hover touch detection through 2 cm air gaps and supports capacitive, inductive, and liquid sensing in a single device. The device also supports waterproofing for harsh environments and reduces system complexity and cost by integrating multiple sensing technologies into a single chip. Infineon PSoC 4000T specifications: MCU Core – 48 MHz Arm Cortex-M0+ CPU Memory – Up […]

Renesas RX260 and RX261 64 MHz RXv3 MCUs target power-efficient touch applications

Renesas RX260 RX261 RXv3 microcontrollers

The Renesas RX260 and RX261 two new 64 MHz microcontrollers part of the high-performance, high-efficiency RX product family with integrated capacitive touch-sensing and high power efficiency in both active and standby modes. The microcontrollers are based on the RXv3 core with a performance score of 355 CoreMark @ 64MHz, which is “2.5 times higher than competing 64 MHz class MCUs.” The chips are also power-efficient, with a consumption rate of 69μA/MHz during active operation and 1μA only in standby mode. According to Renesas, the chips are up to 25% more efficient in active mode and 87% more efficient in standby mode than other 64 MHz class MCUs. Another competing factor is the onboard 8KB of data flash, eliminating the need for external EEPROM. The RX260 and RX261 Group MCUs support noise- and water-resistant capacitive touch via Renesas’ third-generation capacitive touch IP (CTSU2SL). They also integrate an “automatic judgment function” that […]

UniHiker review – A Linux-based STEM education platform with IoT and AI support, Micro:bit edge connector

DFRobot’s UniHiker is a STEM educational platform that was originally launched in China, but now UniHiker is now available worldwide through the DFRobot shop. The company has sent us a UniHiker sample for review, so let’s unpack the kit and learn how to use the UniHiker platform. The main component of the kit is the Linux-powered UniHiker board which features a 2.8-inch resistive touchscreen display and a BBC Micro:bit edge connector, so we can use expansion boards for the Micro:bit board. Let’s start unboxing it together. UniHiker unboxing DFRobot sent us the UniHiker platform by DHL. The package is a familiar-looking DFRobot box in orange color and comes with a plastic box to safely store the UniHiker board and accessories after use. The plastic box contains another plastic box with the board, some 3-pin and 4-pin cables for Gravity ports, and a USB Type-C cable. The UniHiker is like a […]
