Walnut Pi 2B is an Allwinner T527 octa-core SBC with Raspberry Pi 5 form factor and interfaces

Walnut Pi 2B is a single board computer (SBC) powered by an Allwinner T527 octa-core Cortex-A55 SoC with a built-in 2 TOPS AI accelerator that closely follows the Raspberry Pi 5 design for compatibility with most HAT+ expansion boards and accessories. The Walnut Pi 2B SBC ships with 1GB to 4GB LPDDR4 RAM, an optional 32GB eMMC flash, and features a microSD card slot, gigabit Ethernet, four USB ports, a WiFI and Bluetooth module, MIPI DSI/CSI connectors, and the same PCIe FFC connector as found on the Raspberry Pi 5, and a 40-pin GPIO. One of the most obvious differences is that it only comes with one micro HDMI port instead of two on the Pi 5. Let’s check out the specifications to find other changes. Walnut Pi 2B specifications: SoC – Allwinner T527 CPU Octa-core Arm Cortex-A55 processor with four cores @ 1.80 GHz and four cores @ 1.42GHz […]

SO-ARM101 open-source dual robotic arm kit works with Hugging Face’s LeRobot

SO-ARM101 robotic arm with hugging face support

SO-ARM101 “Arm Servo Motor Kit” is an open-source dual robotic arm kit that works with Hugging Face’s LeRobot robotics framework and is designed to interface with NVIDIA Jetson AI modules and computers. It is an update to the SO-ARM100 DIY open-source robotic arm kit introduced last year with LeRobot framework support. The new SO-ARM101 is still comprised of leader and follower arms but features improved wiring to prevent disconnection issues previously seen at joint 3, motors with optimized gear ratios, and a few functionality where the leader arm can now follow the follower arm in real-time, which will be used for reinforcement learning (RL) where a human can intervene and correct the robot’s actions. SO-ARM101 specifications: Degrees of Freedom (DOF) – 6 per Arm Motor control Total servo – 12x STS3215 bus servos (6x for each Arm) Leader Arm 1x (7.4V) 1:345 gear ratio motor for No.2 joints 2x (7.4V) […]

XIAO 2-channel Wi-Fi AC Energy Meter runs ESPHome on ESP32-C6 module, comes with two 100A CT clamps

Seeed Studio’s XIAO 2-channel Wi-Fi AC Energy Meter is an ESP32-C6 (XIAO ESP32-C6) powered power meter with two independent CT clamp (Current Transformer clamp) connectors to safely measure power consumption when placed around one of the wires from an AC cable. We reviewed the SONOFF POW Ring single-channel WiFi CT clamp power meter with eWelink and Home Assistant last year, and before that, we also covered models supporting multiple CT clamps, up to 16 clamps with the Emporia Vue Gen 2 energy monitor. The XIAO 2-channel Wi-Fi AC Energy Meter offers a middle ground with support for two CT clamps measuring up to 35A each. XIAO 2-channel Wi-Fi AC Energy Meter specifications: Wireless module – XIAO ESP32C6 board Wireless MCU – Espressif Systems ESP32-C6 CPU Single-core 32-bit RISC-V clocked up to 160 MHz Low-power RISC-V core @ up to 20 MHz Memory – 512KB SRAM, 16KB low-power SRAM Storage – […]

Cerebro clusterboard supports up to four NVIDIA Jetson, Raspberry Pi CM4/CM5, or Radxa CM5 modules (Crowdfunding)

Cerebro is a modular board / clusterboard designed to take up to four system-on-modules such as NVIDIA Jetson SO-DIMM modules, Raspberry Pi CM4 or CM5, or Radxa CM5. The board integrated a BMC for intercommunication between the CPU modules. The Cerebro was designed out of frustration as the team at Sparklab Solution could not find a solution where boards would work together seamlessly. While there are other clusterboards for Raspberry Pi Compute modules, the Cerebro motherboard provides more flexibility with three M.2 sockets per node, a built-in BMC and optional expandable BMC, KVM support between each node, dual Ethernet, a 10 Gbps USB 3.2 port, and more. Specifications: Compute Modules 4x SODIMM-260 slots Compatibility Nvidia Jetson Orin NX/Nano Raspberry Pi CM4/CM5 via adapter Radxa CM5 via adapter Supports mix and match of different models Storage 2x M.2 key-M slots per node (8x in total) for NVMe SSD 1x MicroSD card […]

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 […]

New color e-paper monitors – 13.3-inch DASUNG Paperlike 13K and 23.5-inch BOOX Mira Pro Color

DASUNG Paperlike 13K ports epaper color monitor

Back in 2023, DASUNG launched its first color E-Ink monitor, quickly followed by BIGME B251 computer and standalone E-Ink monitor. Both were based on the same 23.5-inch E-ink Kaleido 3 color display with 3200×1800 resolution, and were rather pricey at $1,529 (Indiegogo price) and $1,299 (Kickstarter price), respectively. Let’s revisit color e-paper monitors in 2025 with two new models that were just announced: the DASUNG Paperlike 13K 13.3-inch e-ink color monitor and BOOX Mira Pro (Color version) with the same 23.5-inch E-Ink Kaleido as competing monitors launched in 2023. Those monitors are particularly well-suited for people spending long hours in front of the screen, and don’t need to watch video and play games due to the lower refresh and ghosting effect. It’s supposed to be friendlier to eyes, and there’s no blue light. DASUNG PaperLike 13K – 13.3-inch e-ink color monitor Paperlike Paperlike 13K (13KCFT) specifications: Display 13.3-inch Color E-ink […]
