LicheeRV Nano – A low-cost SG2002 RISC-V and Arm camera and display board with optional WiFi 6 and/or Ethernet

When I wrote about the SOPHGO SG2002 (and SG2000) RISC-V, Arm, and 8051 AIoT processor yesterday, I noted several boards were in development, but I had not noticed the Sipeed LicheeRV Nano (Beta) was already available for sale, so let’s have a closer look. It’s an inexpensive, tiny camera and display board running Linux with optional support for WiFi 6 and 10/100M Ethernet connectivity which somewhat reminds me of the Breadbee SBC based on MStar MSC313E Camera SoC. Sipeed also provides accessories such as a camera module and a touchscreen display to quickly get started. LicheeRV Nano specifications: SoC – SOPHGO SG2002 Main core – 1GHz 64-bit RISC-V C906 or Arm Cortex-A53 core (selectable) Minor core – 700MHz 64-bit RISC-V C906 core Low-power core – 25 to 300MHz 8051 MCU core NPU – 1 TOPS INT8, supports BF16 Integrated 256MB DDR3 (SiP) Storage – MicroSD card slot and SD NAND […]

LILYGO T-Panel – A 4-inch HMI display and WiFi, BLE, and 802.15.4 gateway based on ESP32-S3 and ESP32-H2

T-Panel 4-inch ESP32-S3 and ESP32-H2 gateway

LILYGO T-Panel is both a 4-inch HMI display and IoT gateway based on ESP32-S3 WiFi 4 and Bluetooth LE 5 microcontroller and an ESP32-H2 module with Bluetooth LE 5 and an 802.15.4 radio for Zigbee, Thread, and Matter connectivity. Last year, Espressif introduced the ESP-Thread Board Router/Zigbee gateway board with ESP32-S3 and ESP32-H2 to show how both chips could be combined to create IoT gateways. But I don’t think I had seen a company design a product based on both ESP32-S3 and ESP32-H2 until I saw the T-Panel which also includes an RS485 interface and Qwiic expansion connectors for good measure. T-Panel specifications: Wireless chips/modules Wireless SoC – ESP32-S3R8 dual-core Tensilica LX7 microcontroller @ 240 MHz 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Wireless module – ESP32-H2-MINI-1 module MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 […]

Raspberry Pi 5 industrial HMI displays gain M.2 NVMe SSD, RS232/RS485 interfaces, audio input/output jacks

Raspberry Pi 5 industrial HMI with RS232/RS485 audio input/output jacks

EDATEC ED-HMI3020 is a family of Raspberry Pi 5-based industrial HMI displays that build upon the earlier ED-HMI3010 panel PCs by adding an M.2 socket for NVMe SSD, RS232 and RS485 interfaces, as well as 3.5mm audio input and output jacks. The new models are still offered with either a 7-inch (1024×600) or 10.1-inch (1200×800) touchscreen display, a Raspberry Pi 5 with 4GB or 8GB RAM with all main ports (HDMI, Ethernet, USB) accessible externally, and support for an optional 8MP front-facing camera. ED-HMI3020 specifications with differences again ED-HMI3010 highlighted in bold or strikethrough: SoC – Broadcom BCM2712 CPU – Quad-core Arm Cortex-A76 processor @ 2.4 GHz with crypto extensions, 512KB per-core L2 caches, 2MB shared L3 cache GPU – VideoCore VII GPU @ 800 MHz with support for OpenGL ES 3.1, Vulkan 1.2, 4Kp60 HEVC decoder System Memory – 4GB or 8GB LPDDR4X-4267 SDRAM Storage MicroSD card socket M.2 […]

How I “fixed” the display on Lichee Console 4A terminal

When I wrote a hands-on post about Lichee Console 4A RISC-V development terminal I noted the display would sometimes have strange effects or simply go black. I’ve now fixed the issue, and I was just probably unlucky since the issue must be rare, but I’ll still document it in case somebody encounters a similar problem and for fun! First, the video below shows what I would see on my terminal after using it for a few minutes. Since then, the display has gone completely dark, and all I see is the backlight, but I can still access the device through an SSH terminal. It looks like a bad connection issue, but I still contacted Sipeed and they told me it must have been the display connector. So I turned off the device and reopened the enclosure to remove and reinsert the cable for the display as shown in the photo […]

Review of Elecrow’s 3.5-inch and 7.0-inch ESP32 display modules using Arduino programming

Using the ESP32 7.0-inch display as a dashboard

Hello, I’m excited to review the ESP32 display modules and HMI touchscreens from Elecrow with sizes ranging from 2.4 to 7.0 inches. For this review, Elecrow kindly provided me with both 3.5-inch and 7.0-inch models. While their screens differ in size, both modules share several components, such as the ESP32 microcontroller, making them adaptable options for a variety of projects. The Elecrow 7.0-inch display module is powered by the ESP32-S3-WROOM-1-N4R8 module equipped with an ESP32-S3 dual-core LX6 32-bit microprocessor, 4 MB of flash, 384 kB of ROM, and 512 kB of SRAM. This microcontroller supports both WiFi and Bluetooth for wireless communication. The 7.0-inch display itself is a capacitive touch screen with a resolution of 800×480 pixels. The display is controlled by the EK9716BD3/EK73002ACGB driver and is compatible with LVGL for additional functionality. In the case of the 3.5-inch display module, the main difference is the use of the ESP32-WROOM-32-N4 […]

LILYGO T4-S3 board combines 2.41-inch AMOLED touchscreen display with ESP32-S3R8 microcontroller

LILYGO T4-S3 is yet another ESP32-S3 board with an integrated display, but the main difference here is the 2.41-inch AMOLED touchscreen display with brighter colors than typical TFT displays. It’s actually not the first ESP32-S3 board with an AMOLED display from LILYGO as we previously covered the T-Track and T-Display-S3 AMOLED boards from the company, but the new T4-S3 has a larger 2.41-inch display with touchscreen function and an aspect ratio that may make it more suitable for a wider range of HMI applications. LILYGO T4-S3 specifications: SoC – Espressif ESP32-S3R8 CPU – Dual-core Tensilica LX7 microcontroller up to 240 MHz with vector instructions for AI acceleration Memory – 8MB PSRAM Wireless – WiFi 4 and Bluetooth 5.0 LE + Mesh connectivity Storage – 16MB SPI flash, MicroSD card socket Display – 2.41-inch RGB AMOLED touchscreen display with 600×450 resolution (QSPI controller) with 800cd/m2 brightness, 36.2 x 48.96mm active […]
