So, we started survey for&nbsp;components for&nbsp;ODROID-W2. Finding out the right CPU was the key of this project. Our original target was similar cost and similar performance as ODROID-W. But we realised that we cannot make ODROID-W2 once we reached to Amlogic S805 quad core processor. The performance of Amlogic S805 ARM®<span style="font-size: 10pt;">&nbsp;Cortex</span>®<span style="font-size: 10pt;">-A5(ARMv7) 1.5Ghz&nbsp;quad core processor is outperforming Broadcom BCM2835 ARM11 700MHz.&nbsp;</span><span style="font-size: 10pt;"><br></span><br>Here is the comparisons to give you better understanding of ODROID-C1.<br><br><b>ODROID-C1 vs Raspberry Pi B+&nbsp;</b><br><br>Both are Linux-friendly, $35 ARM®<span style="font-size: 10pt;">&nbsp;single-board computers for various applications and purposes.&nbsp;</span><br><br><b>Hardware Comparison</b><br><br>The ODROID-C1 has many advantages over the Raspberry Pi. The processor is an S805 1.5GHz Quad-core from Amlogic with 1GByte DDR3 RAM, Gigabit Ethernet and IR-receiver. The size of this computer is still only 85 x 56 mm with a weight of 40g, and offers silent operation, 2~3W average power usage, and instant portability, since it fits in a shirt pocket.&nbsp;<br><br>One powerful feature of the ODROID-C1 is the row of GPIO (general purpose input/output) pins along the edge of the device. These pins are a physical interface between the board and the outside world. The 40pin interface header includes SPI, I2C, UART, ADC and GPIO function.<br><br>An SD 3.01 standard compatible UHS-1 Micro-SD card, as well as the faster eMMC module, can be ordered with the ODROID-C1, and arrives with the popular Ubuntu operating system already installed. Insert the SD card into the slot, connect a monitor, a keyboard, a mouse, Ethernet and power cable, and that’s all you need to do to use the ODROID-C1! Browse the web, play games, run office programs, edit photos, develop software, and watch videos right away.&nbsp;<br><br>The RTC, IR receiver and ADC features on the ODROID-C1 offer many options for building great DIY projects<br><br><table width="980" align="left" bordercolor="gray" bgcolor="" border="1" cellspacing="0" cellpadding="5" style="margin: 0px; padding: 0px; border-collapse: collapse; border-spacing: 0px;"><tbody><tr><td style="text-align: center;"></td><td style="text-align: center;">ODROID-C1</td><td style="text-align: center;">RPi Model-B+</td></tr><tr><td style="text-align: center;">CPU</td><td><div style="text-align: center;"><span style="font-size: 10pt;">Amlogic S805 SoC</span></div><div style="text-align: center;"><span style="font-size: 10pt;">4 x ARM</span><span style="font-size: 10pt;">®</span><span style="font-size: 10pt;">&nbsp;Cortex</span><span style="font-size: 10pt;">®</span><span style="font-size: 10pt;">-A5 1.5GHz</span></div><div style="text-align: center;"><span style="font-size: 10pt;">ARMv7 Architecture @28nm wafer</span></div></td><td><div style="text-align: center;"><span style="font-size: 10pt;">Broadcom BCM2835</span></div><div style="text-align: center;"><span style="font-size: 10pt;">1 x ARM11 700MHz</span></div><div style="text-align: center;"><span style="font-size: 10pt;">ARMv6 Architecture @40nm wafer</span></div></td></tr><tr><td style="text-align: center;">GPU</td><td style="text-align: center;">2 x ARM®<span style="font-size: 10pt;">&nbsp;Mali</span>™-<span style="font-size: 10pt;">450MP 600MHz</span></td><td style="text-align: center;">1 x VideoCore IV 250MHz</td></tr><tr><td style="text-align: center;">RAM</td><td style="text-align: center;">1GB 32bit DDR3 792MHz</td><td style="text-align: center;">512MB 32bit LP-DDR2 400MHz</td></tr><tr><td style="text-align: center;">Flash Storage</td><td style="text-align: center;">Micro-SD UHS-1@100Mhz/SDR50 or eMMC storage option</td><td style="text-align: center;">Micro-SD @50Mhz/SDR25, No eMMC storage option</td></tr><tr><td style="text-align: center;">USB2.0 Host</td><td style="text-align: center;">4 Ports</td><td style="text-align: center;">4 Ports</td></tr><tr><td style="text-align: center;">USB2.0 Device / OTG</td><td style="text-align: center;">1 Port for Linux USB Gadget driver</td><td style="text-align: center;">No</td></tr><tr><td style="text-align: center;">Ethernet/LAN</td><td style="text-align: center;">10/100/1000 Mbit/s</td><td style="text-align: center;">10/100 Mbit/s</td></tr><tr><td style="text-align: center;">Video Output</td><td style="text-align: center;">HDMI</td><td style="text-align: center;">HDMI / Composite RCA</td></tr><tr><td style="text-align: center;">Audio Output</td><td style="text-align: center;">HDMI</td><td style="text-align: center;">HDMI / 3.5mm Jack</td></tr><tr><td style="text-align: center;">Camera Input</td><td style="text-align: center;">USB 720p</td><td style="text-align: center;">MIPI CSI 1080p</td></tr><tr><td style="text-align: center;">Real Time Clock</td><td style="text-align: center;">YES (On-board RTC)</td><td style="text-align: center;">No(unless using an add-on module)</td></tr><tr><td style="text-align: center;">IR Receiver</td><td style="text-align: center;">YES (On-board IR Sensor)</td><td style="text-align: center;">No(unless using an add-on module)</td></tr><tr><td style="text-align: center;">IO Expansion</td><td style="text-align: center;">40pin port (GPIO/UART/SPI/I2C/ADC)</td><td style="text-align: center;">40pin port (GPIO/UART/SPI/I2C/I2S)</td></tr><tr><td style="text-align: center;">ADC</td><td style="text-align: center;">10bit SAR 2 channels</td><td style="text-align: center;">No(unless using an add-on board)</td></tr><tr><td style="text-align: center;">Size</td><td style="text-align: center;">85 x 56mm (3.35” x 2.2”)</td><td style="text-align: center;">85 x 56mm (3.35” x 2.2”)</td></tr><tr><td style="text-align: center;">Weight</td><td style="text-align: center;">40g (1.41 oz)</td><td style="text-align: center;">42g (1.48 oz)</td></tr><tr><td style="text-align: center;">Price</td><td style="text-align: center;">$35</td><td style="text-align: center;">$35</td></tr></tbody></table></td></tr><tr><td><br><b><br>Computing performance comparison<br></b><br>We ran a simple, popular benchmark called Unix-Bench (version 5.1.3) to compare the performance of the two boards.
