“New” Raspberry Pi Zero WH Launched with Pre-Soldered Headers

Raspberry Pi Zero W was launched in February 2017 for $10 as an update to RPi Zero adding WiFi and Bluetooth connectivity. The Raspberry Pi foundation has now announced a new model called Raspberry Pi Zero WH. What does not extra H mean? H Bridge? nope. Hybrid? nope. WH like in white PCB? re-nope. H means the 40-pin header is soldered. It can be more convenient for people who don’t own a soldering iron, or don’t feel confident soldering on their own. Apart from the header, Raspberry Pi Zero WH specifications remain identical to the W version: SoC – Broadcom BCM2835 ARM11 processor @ 1GHz with VideoCore IV GPU System Memory – 512MB RAM Storage – microSD slot Video Output – mini HDMI port and composite video (via 2 unpopulated pins) Connectivity – 802.11 b/g/n WiFi and Bluetooth 4.0 USB – 1x micro USB OTG port, 1x micro USB port […]

HiKey 960 Android Development Board Gets a 4GB RAM Version for $250

Hikey 960 development board is one of the most powerful Arm boards on the market thanks to Huawei/Hisilicon Kirin 960 octa-core processor with four ARM Cortex A73 cores, four Cortex A53 cores, and a Mali-G71 MP8 GPU, fast storage with 32GB UFS 2.1 flash, and 3GB LPDDR3 memory. Like the earlier Hikey (620) board, the board is also an official reference board for AOSP, so you should be able to run the latest Android version, and also play with sensors using Neonkey SensorHub 96Boards mezzanine board. If you are somehow limited by the 3GB RAM on the board, you can rejoice as Seeed Studio has just launched a 4GB RAM version selling for $249, or about $10 extra. Note that shipping is only scheduled for February 2, 2018, so those are pre-orders. The rest of the specifications for Hikey 960 4GB RAM version are unchanged: SoC – Huawei Kirin 960 […]

Quokka IoT FPGA Board is Programmable with C# Language (Crowdfunding)

Quokka FPGA IoT Controller is a board based on Altera Cyclone IV FPGA with a WiPy module for connectivity, and various I/Os that allows you to make robotics projects for example. While you could program the FPGA using VHDL, the developer – Evgeny Muryshkin – also designed Quokka Development Toolkit (QDT), a cloud-based SaaS, allowing to program FPGA with a high-level programming language, currently C#, so that software people can more easily become involved in FPGA development. Quokka IoT (preliminary) hardware specifications: FPGA – Intel Altera Cyclone IV, 6K logic elements, EP4CE6E22C8 Clock – 50MHz Connectivity – WiFi via WiPy module Expansion 40x GPIO (3 banks by 8 pins, with direction and voltage (3.3V or 5V) configuration, 16 raw IO pins 3.3V) 2x Dual Channel 10 bit ADC (3.3V) 2x Dual Channel 10 bit DAC (3.3V) H-Bridge for DC motors with support for external power Power Supply – 5-24V DC input […]
