uSVC Arduino VGA board – a portable and programmable retro-gaming console (crowdfunding)


Itaca Innovation previously launched uChip, an Arduino-compatible board that has a Cortex M0+ MCU that features 0.3” spacing between rows. Now, next-hack joined Itaca Innovation to come up with an expansion board for uChip. The uChip Simple VGA Console (uSVC) Arduino based retro-gaming console is open hardware and is a programmable console. It will allow creating and playing retro “9-bit” games with standard USB controllers and keyboards. You will get one uChip (pre-soldered) and the uSVC game loader pre-programmed, a PCB with a pre-soldered SMD MicroSD card reader. It also includes all of the components needed to build your uSVC, and Bill of Material (BOM) and assembly drawings will also be provided. uSVC Specifications uChip is the heart of uSVC (48 x 86 x 17 mm), with a Microchip SAMD21 Arm Cortex-M0+ MCU clocked @ 48 MHz (Arduino Zero compatible). A VGA output of 57 Hz vertical frequency, 30 kHz […]

ESP8266 based Wireless Air Quality & Environmental Monitors Teardown – Sonoff SC and vThings CO2 Monitor

The mailman delivered two parcels today, and interestingly enough they have a similar functionality measuring air quality and environmental data such as temperature. The first package was ITEAD Studio Sonoff SC environmental sensor with ESP8266, an Atmel MCU, DHT11 temperature & humidity sensor, a dust detector, a light sensor, and a microphone, while the second was v-Air Monitor vThings CO2 monitor v3 also based on ESP8266 with a CO2 sensor and other optional sensors. I’ll test both with their stock firmware later on, but today I’ll have a look at the hardware design. v-Air Monitor vThings CO2 monitor specifications While I’ve already written about Sonoff SC, it’s the first time I cover v.Air Monitor products, so let’s start with the specifications of vThings CO2 Monitor v3: SoC – Espressif ESP8266 WiSoC Connectivity 802.11 b/g/n WiFi Optional RF315 / 433 MHz RF module Sensors CO2 Sensor (one of them) CM1106 NDIR […]

Microchip Atmel ATtiny417/814/816/817 tinyAVR MCUs Include Core Independent Peripherals (CIPs)

Microchip’s latest Atmel tinyAVR MCUs combine Atmel 8-bit AVR core with CIPS (Core Independent Peripherals) normally found in the company’s PIC MCUs. Since Atmel’s purchase by Microchip, I believe this is the first time the company leverages features from both MCU families. The four new ATtiny MCUs come with 4 to 8 KB flash, and up to 24 pins: ATtiny417 – 8-bit Atmel AVR MCU with 4KB Flash, 256 bytes SRAM, 128 bytes EEPROM, 20MHz/20 MIPS, two 16-bit timer/counters, one 12-bit timer/counter, RTC, USART, SPI, Two-wire Interface (I2C), 10-bit ADC, 8-bit DAC, analog comparator, accurate internal oscillators and multiple calibrated voltage references, Custom Logic, 10-bytes unique ID, and 24 pins ATtiny814 – Same as above but with 8KB flash, 512 bytes SRAM, Peripheral Touch Controll (PTC), and 14 pins ATtiny816 – Same key features as ATtiny814 but with a 20-pin package with more I/Os ATtiny817 – Same key features as […]

Atmel Introduces SAMA5D2 Cortex A5 SoC with Extended Temperature Range, Lower Power Consumption

Today, the news broke out that Atmel will be bought by Dialog Semiconductor for about $4.6 billion. The Anglo-German company is little known as their main products are PMIC, audio and connectivity chips, but they’ve still managed to get the financing to purchase Atmel. But that’s not the purpose of the post today, and instead I’ll cover a new SAMA5 Cortex A5 SoC recently announced by the company, targeting industrial Internet of Things, wearables and point of sale applications. SAMA5D2 key features and benefits: ARM Cortex-A5 core running at 500MHz (785DMIPS).
