VoCore is open hardware and runs Linux(OpenWrt). It has 128MB DDR, WIFI, USB, UART, SDXC, I2C, SPI, 20+ GPIOs but only one inch square(25.8mm). It will help you to make a smart house, study embedded system or even make the tiniest router in the world.
You will not only get the VoCore but also its hardware design including schematic, circuit board, bill of materials and source code of all applications. You are able to control EVERY BIT of your VoCore.
We invite you join us, help our community improve this open source hardware and use your creative skills to make a more wonderful Internet of Things!


Tiny Size: One square inch, easy to embed to devices.
OpenWrt: Easy to code; super stable, three years no reboot.
Low Cost: low cost, less than 1watt, unmatched performance.
Interfaces: Hardware support USB, Ethernet, SD, I2C, SPI etc.
OpenSource: Both software and hardware, totally FREE
Long Life: Keep production over 10 years, fast email support.
El área aproximada es 3.75 unidades cuadradas. (El área real por integral es ( \frac83 \approx 2.666 ), por lo que esta aproximación por derecha es una sobreestimación).

Use a right Riemann sum with (n=5) to approximate (\int_0^2 e^x dx). Compute error. Inside this PDF, you will find: [ c_1 = \frac1+22 = 1
En lugar de calcular el área de forma exacta (lo cual requiere integración), dividimos la región en rectángulos delgados. Al sumar las áreas de estos rectángulos, obtenemos una aproximación del área total. A medida que el número de rectángulos (
