Olimex ESP32-POE2 board offers up to 25W for power-intensive applications

The Bulgarian hardware manufacturer, Olimex, has designed a new ESP32 board with Power over Ethernet (PoE) functionality. The Olimex ESP32-POE2 board builds on the original ESP32-POE and features the same ESP32-WROOM-32 microcontroller module with Wi-Fi and Bluetooth connectivity. However, it supports up to 25W power delivery from the Ethernet port via PoE and can be used in more demanding projects. The Olimex ESP32-POE2 board features a low-power design and consumes only 200µA in deep sleep mode. The board can be powered via USB-C, Ethernet, or Li-Po battery. The Ethernet interface is built on Texas Instruments’ TPS2378PW chip with IEEE 802.3at classification and legacy PoE support. Powering with PoE requires at least 37V DC for seamless operation. Two proprietary connectors (UEXT and EXT1) can be used to add sensors and other modules and expand the board’s operation for IoT projects. Users can select between 24V/0.75A or 12V/1.5A power output, with a […]

Ronetix launches NXP i.MX93 SoMs in SMARC and OSM-L form factors

Austrian embedded equipment manufacturer, Ronetix, has released two i.MX93 system-on-modules (SoMs): the RNX-iMX93-OSM that follows the Open Standard Module (OSM) form factor, and the RNX-iMX93-SMARC compliant with the SMARC 2.1 (smart mobility architecture) standard. Ronetix i.MX93 SoMs are powered by the NXP i.MX93 processor featuring a 64-bit dual-core Arm Cortex-A55 application processor running at 1.7GHz and a Cortex-M33 core running at 250MHz for low-latency and real-time tasks. The SoC supports up to 2GB LPDDR4 RAM and 512GB eMMC storage, and the integrated Arm Ethos-U65 microNPU offers up to 0.5 TOPS of computing power for machine vision applications and intelligent energy management (IEM). Applicable for industrial automation and IoT, the SoMs also feature two CAN and Ethernet interfaces to aid high-speed data transfer. Other hardware featuring the i.MX93 that we have covered recently include the ADLINK OSM-IMX93, MaaXBoard OSM93, and Ka-Ro Electronics’ QS93. The RNX-iMX93-SMARC system-on-module comes in 82 x 50mm […]

SC730 module from Small Computer Central features the now-discontinued Zilog Z80 CPU

Small Computer Central has released a new module kit, the SC730, for the 80pin-RCBus backplane which features the widely-used 8-bit Zilog Z80 CPU and a memory management unit. The Zilog Z80 is an 8-bit microprocessor created to be compatible with the Intel 8080 microprocessor while offering more advanced features such as built-in DRAM refresh, a better interrupt system, and non-multiplexed buses. The Z80 microprocessor was widely used for various applications between the 70s and the 80s and is still quite popular among retro computing enthusiasts today. Cousins’ SC730 module kit is designed to fit into an 80-pin socket on an RCBus backplane. The module is built to be used with a memory module as part of a complete computer system. The memory management unit (MMU) is compatible with a 1MB linear memory module such as the SC721. It maps a fixed 32KB bank of RAM to the top of the […]

Louder Raspberry Pi is an open-source home media center that is powered by Raspberry Pi Zero and a TI TAS5805M DAC

Louder Raspberry Pi is an open-source home media center based on a combination of the Raspberry Pi Zero W or Zero 2 W and the Texas Instruments TAS5805M DAC. It is an audio entertainment platform created by Andriy Malyshenko of Sonocotta, a Polish electronics hobbyist and maker. Louder Raspberry Pi incorporates the computing power of the Raspberry Pi Zero and the Hi-Fi audio processing capabilities of TI’s TAS5805M DAC in a compact, aluminum case. The device delivers up to 25W per channel stereo output and is powered via a 65W+ USB-C PD3.0 adapter. It is “aimed to be paired with medium-to-large speaker systems” and supports both Wi-Fi and Ethernet. The Raspberry Pi board was selected over other lightweight alternatives due to the ease of development it offers. The Raspberry Pi Zero board is small enough to make for an overall compact device and powerful enough to handle the demands of […]

FOCn ESP32-S3-based, medium-power BLDC driver module supports SimpleFOC

European engineer, Matej Planinšek of PLab, has developed the FOCn — a medium-power BLDC driver module based on ESP32-S3 WiSoC capable of delivering up to 10A of continuous current. It is compatible with the SimpleFOC Arduino library making it easier to control BLDC (brushless direct current) and stepper motors with the field-oriented control algorithm. The developer was inspired to create the FOCn module when their search for a custom-made, SimpleFOC-compatible driver module that met all their requirements failed. The name is related to field-oriented control (FOC) and also means “face slap” in Slovenian, Matej’s native language. The driver module is based on the ESP32-S3 dual-core XTensa LX7 microcontroller which provides Wi-Fi and Bluetooth connectivity. The microcontroller further supports ESP-NOW, a low-power and low-latency communication protocol, which makes it possible for multiple FOCn boards to talk to one another. FOCn driver module specifications: MCU – ESP32-S3 dual-core XTensa LX7 microcontroller @ […]
