$10 Digistump Oak ESP8266EX Board is Arduino Compatible, Connects to the Cloud, and More (Crowdfunding)

A few years ago, I wondered why adding Wi-Fi to Arduino had to be rather expensive ($40+), and why there weren’t any low cost and small form factor Wi-Fi boards for embedded applications. But we’re now in 2015, embedded is “dead” giving rise to IoT, and I’m left wondering how it’s possible to make IoT Wi-Fi modules that cheap, and whether people will ever stop churning out cheap Wi-Fi boards, as I’m flooded with such news weekly… So when I saw yet another ESP8266 board on Kickstarter I was about to dismiss it, but since it was made by Digistump, that has an active community with their other products like DigiSpark Pro or DigiX, I decided to have a closer look. Digistump Oak hardware specifications: MCU – Espressif ESP8266EX 32-bit microprocessor @ 80MHz (overclockable up to 160MHz)  with 1MB ROM (~300KB available for user code), 64KB RAM, 512 bytes EEPROM […]

NodeMCU is both a Breadboard-Friendly ESP8266 Wi-Fi Board and a LUA based Firmware

NodeMCU is a LUA based interactive firmware for Expressif ESP8622 Wi-Fi SoC, as well as an open source hardware board that contrary to the $3 ESP8266 Wi-Fi modules includes a CP2102 TTL to USB chip for programming and debugging, is breadboard-friendly, and can simply be powered via its micro USB port. Let’s checkout the hardware first. The latest version of the board (V1.0) has the following specifications and features: Wi-Fi Module – ESP-12E module similar to ESP-12 module but with 6 extra GPIOs. USB – micro USB port for power, programming and debugging Headers – 2x 2.54mm 15-pin header with access to GPIOs, SPI, UART, ADC, and power pins Misc – Reset and Flash buttons Power – 5V via micro USB port Dimensions – 49 x 24.5 x 13mm The hardware documentation for the board can be found on nodemcu-devkit repo, including schematics and PCB layout designed with Altium Designer, […]

Ambarella Unveils SL2m IP Camera Reference Design Promising up to 6 Months of Battery Life

Ambarella S2Lm IP Camera SoC features a Cortex A9 CPU core, encodes video with H.264 up to 3Mp30 / 1080p30, and targets  consumer and entry-level IP Camera designs. The company recently launched a new battery-powered IP camera reference design based on the solution that promises up to 6 months battery life, and can record Full HD video in less than 500ms from wake up, making ideal for battery operated security cameras. A Linux SDK is also provided with reference implementations for low-power standby operation, wake-on-Wi-Fi and fast boot to Linux. Unfortunately, that’s about all we know about the reference design, so instead I’ll have a look at the processor, and SL2m IP camera evaluation board. Ambarella SL2m SoC specifications: CPU – ARM Cortex-A9 processor with 32KB/32KB I/D and 128 KB L2 Cache, NEON and FPU, Crypto Engine – AES/3/DES/SHA-1/MD5 DSP / VPU –  Ambarella Image and Video DSPs Sensor and […]

AlphaScale ASM9260 ARM9 Processor Details and Development Board

Yesterday, as I wrote a Linux 4.0 Changelog, I noticed a new ARM processor called AlphaScale ASM9260, and I thought it might be interesting to find out more. A Google search would only return results from the Linux kernel mailing list and mirrors, so I checked out the code a bit to find out its an ARM9 processor made by AlphaScale Integrated Circuits Systems, Inc, based in Wuxi, China. The company website alphascale.com does not work, but I found out the processor is sold on Taobao for 38 RMB (~$6), and there’s also a development board (ASM9260DVK) for 498 RMB or about $80, and that’s basically the only two links were I could find any details. AlphaScale ASM9260T is arm ARM926EJS processor clocked at 240 MHz, 16GN I-cache and D-cache, 8KB SRAM, with the following peripherals: 32-bit SDRAM/NOR interface MLC NAND 24-bit ECC 2x USB 2.0 OTG, 2x USB 2.0 […]

How to Program STMicro STM8S $1 Board in Linux

In January, I discovered there was such thing as a one dollar development board based on STMicro STM8S103F3P6 8-bit MCU with 1KB SRAM, 8KB flash, and 640 bytes EEPROM, some GPIOs as well as I2C, UART, SPI, ADC, and PWM signals. Links to documentation and source code were provided, but development tools were only Windows based. However, one of my reader informed me SDCC (Small Devices C Compiler) supported STM8, and development in Linux should be feasible. So I decided to buy the board on eBay for $1.62, as well as an ST_link V2 programmer for STM8 / STM32 for $4.52 in order to flash the firmware. The board came pretty quickly, i.e. within 2 to 3 weeks. But due to a lost package, the programmer took nearly 3 months to reach me, as the seller had to re-send after I failed to receive it within 2 months. It comes […]
