M5Stack Tab5 Review – Part 1: Unboxing, teardown, and first try of the ESP32-P4 and ESP32-C6 5-inch IoT devkit

I’ve just received a review sample of the M5Stack Tab5 ESP32-P4 IoT development kit, which looks like a small tablet with a 5-inch touchscreen display, a 2MP front-facing camera, an ESP32-C6 WiFi 6, Bluetooth, and 802.15.4 wireless module, and various expansion interfaces. Today, I’ll go through an unboxing, a (partial) teardown, and have a quick try with the default firmware and GUI, before checking out how to program the device in the second part of the review. M5Stack Tab5 unboxing I received the Tab5 in its retail package along with an M5Stack-branded transparent sticky tape roll. Not sure why, but thanks M5Stack, sticky tape is always useful, so appreciated! The bottom side of the package has all the key features and specifications that we already covered in our article about the Tab5. The package contains the Tab5 itself, a 2,000mAh/14.8Wh battery, and a cable with six wires for the ExtPort2 […]

M5Stack Tab5 is a tablet-like ESP32-P4 IoT development kit with a 5-inch touchscreen display and front-facing camera

The M5Stack Tab5 may look like a small tablet, but it’s an ESP32-P4 IoT development kit with a 5-inch touchscreen display, a 2MP front-facing camera, an ESP32-C6 WiFi 6, Bluetooth, and 802.15.4 wireless module, and a range of interfaces. Those include USB Type-A and Type-C ports, an RS485 interface, a STAMP pad to connect an LTE Cat M/NB-IoT or LoRaWAN module, and expansion connectors including a Grove module, a 30-pin M5Bus header, and a GPIO_EXT connector. The Tab5 is also equipped with a built-in speaker and dual-microphone array, and the ESP32-P4 development kit is powered by a removable battery with charging support. M5Stack Tab5 specifications: Microcontroller – Espressif Systems ESP32-P4NRW32 CPU Dual-core 32-bit RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz with 8KB of zero-wait TCM RAM Memory 768 KB HP L2MEM […]

OneChipBook-12 is a Cyclone EP1C12Q FPGA development platform with a built-in display and mechanical keyboard

It may look like a netbook from 10 years ago, but the OneChipBook-12 from “8086YES!” is instead an Altera Cyclone EP1C12Q FPGA development platform with a VGA display (LCD form iPad 2), a PS/2 QWERTY mechanical keyboard, a battery, and a few ports. While the OneChipBook-12 is sold as a blank FPGA development platform “with no predefined functionalities”, the hardware is similar to One Chip MSX (1chipMSX), Zemmix Neo, and uMSX systems, which are modern MSX2+ clones, and that’s the main reason people are purchasing the device. OneChipBook-12 specifications: FPGA Altera Cyclone EP1C12Q240 (from the obsolete Cyclone I family) 12,060 LEs 239,616 bits RAM System Memory – 32MB SDRAM Storage – SD card slot (FAT16 file system supported) Display – 1024×768 VGA display Video Output – VGA, S-Video, and CVBS Output interface Audio – Stereo speakers, audio output jack (8), volume control knob (9) USB – USB Type-A port […]

Canonical releases Ubuntu 24.04 Desktop image for the Qualcomm DragonWing QCS6490 and QCS5430 processors

Canonical has just released a publicly available Ubuntu 24.04 Desktop beta image for the Qualcomm DragonWing QCS6490 and QCS5430 processors, and more specifically for the Qualcomm RB3 Gen 2 Vision Kit (QCS6490) and Qualcomm RB3 Gen 2 Lite Vision Kit (QCS5430). This adds to the existing Ubuntu 24.04 Server image for the Qualcomm vision kits, and Canonical says the unified image is currently designed for developers, ODMs/OEMs, and customers who want to evaluate the solution, and certified versions of Ubuntu 24.04 Desktop and Server images are coming soon with long term support and maintenance. Canonical explains the image enables the full Ubuntu Desktop experience at the edge with “powerful AI acceleration with high-performance graphics” (so I assume that means GPU and NPU are already supported), enhanced camera and multimedia capabilities, sensor integration, and various performance optimizations of the DragonWing family. So the way I read the announcement is that contrary […]

ESP32-C5 dual-band WiFi 6 SoC enters mass production, ESP32-C5-DevKitC-1 board launched for $15

Espressif Systems has just started mass production of the ESP32-C5 RISC-V wireless microcontroller with dual-band (2.4/5 GHz) WiFi 6, Bluetooth LE, and 802.15.4 (Zigbee, Thread) connectivity. The ESP32-C5-DevKitC-1 development is now available for about $15 on AliExpress, and should soon show up on the company’s Amazon store. So far, WiFi-capable Espressif microcontrollers have only supported 2.4 GHz WiFi since it’s cheaper and offers better range for IoT applications, but some applications may benefit from 5 GHz WiFi, so the company unveiled the ESP32-C5 dual-band WiFi 6 and BLE RISC-V MCU in June 2022. Design probably took longer than expected, but we noted documentation for an ESP32-C5 beta board in March 2024, and finally, the company has just announced that mass production has started. We’ll have a closer look at the ESP32-C5-DevKitC-1 board in this article, since it is different from the beta board. ESP32-C5-DevKitC-1 specifications: Wireless module – ESP32-C5-WROOM-1 SoC […]

Zalmotek RA6M1, RA8M1, and RZ/A3U SoMs follow Adafruit Feather form factor, support carrier board for robotics and industrial control

Romanian company Zalmotek has recently introduced three new SoMs, the RA6M1, RA8M1, and RZ/A3UL, and a modular carrier board designed for embedded applications such as robotics, industrial control, and edge computing. There are a few things that I find interesting about this setup. The SoM comes in Adafruit Feather form factor and, as a result, supports various Adafruit FeatherWings. The modular carrier board supports the Dynamixel motor driver module, the Particle M-SoM breakout module, Ethernet, and CAN modules. The RA6M1 Feather SoM is powered by a Renesas RA6M1 Arm Cortex-M4 CPU at up to 120 MHz, with 512 KB flash and 96 KB SRAM while the RA8M1 Feather SoM features a Renesas RA8M1 64-bit Arm Cortex-M85 running at up to 360 MHz with 128 Mbit SPI flash, the RZ/A3UL Feather SoM is based on a Renesas RZ/A3UL 64-bit Arm Cortex-A55 CPU at up to 1 GHz, with 512 Mbit OctaFlash […]

SPARK Microsystems SR1120 UWB ultra-low-power transceiver delivers up to 41 Mbps throughput

SPARK Microsystems SR1120 is the company’s second-generation ultra-wideband (UWB) wireless transceiver capable of up to 41 Mbps throughput at ultra-low power and up to 100 times lower power ranging than UWB competitors. The Canadian company also highlights the outperformance of their UWB solution over Bluetooth with the new SR1120 offering 40 times higher data rates than Bluetooth chips, while consuming 25 times less power than Bluetooth and offering 60 times lower latency. However, readers should note that Bluetooth LE is supposed to support up to 2 Mbps, so it should (only) be up to about 20 times faster, and Bluetooth HDT is coming soon with data rates of up to 7.5 Mbps to further narrow the gap. SPARK SR1120 key features and specifications: Compliant with the upcoming IEEE 802.15.4ab low-energy UWB PHY standard Dynamically reconfigurable UWB spectrum 6.2–9.5 GHz band Up to 3 dBm TX power RX sensitivity of -81 […]
