وقتی قیمت بالای لپتاپ
نوونا رو دیدم تا به اونجام سوخت! مطمئنا با تجربه ای که از قیمت تمام شده بوردهای وارداتی کوچکی مثل رزبری به بازار ایران داریم، این یکی اگر به مرحله ساخت برسه و قرار باشه به بازار ایران راه پیدا کنه، باید خونه و ماشینمون رو بفروشیم شاید بتونیم یکی بخریم.
حالا با توجه به اینکه نقشه های ساختش موجوده:

https://github.com/xobs/novena-linuxاگر قرار باشه همینجا مشابهش رو برای خودمون بسازیم، چند در میاد و اصلا قطعات مورد نیازش موجوده؟ (نه دقیقا همون سخت افزار، مشابهش در همون ابعاد هم موجود باشه عالیه)
به اطلاعات بچه های کف بازار نیاز داریم.مشخصات بوردش از این قراره:
Features:
Freescale iMX6 CPU
Quad-core Cortex A9 CPU with NEON FPU @ 1.2 GHz
NDA-free datasheet and programming manual

2x USB 2.0 ports, supporting high-current (1.5A) device charging
1Gbit ethernet
Fun features:
100 Mbit ethernet — dual Ethernet capability allows laptop to be used as an in-line packet filter or router
USB OTG — enables laptop to spoof/fuzz ethernet, serial, etc. over USB via gadget interface to other USB hosts
Utility serial EEPROM — for storing crash logs and other bits of handy data
Spartan-6 CSG324-packaged FPGA — has several interfaces to the CPU, including a 2Gbit/s (peak) RAM-like bus — for your bitcoin mining needs. Or whatever else you might want to toss in an FPGA.
High-speed I/O expansion header -- useful for implementing a wide variety of functions, from simple GPIO breakouts to high-performance analog data sampling front-ends
Ships with pre-installed:
4GiB DDR3 SO-DIMM
4GiB (minimum) microSD card with basic Debian install
Ath9k (blob-free firmware) mPCIe wifi card, 802.11n b/g 1T1R
16V, 3.75A power supply (100-240V 50/60Hz input), with IEC C7 to NEMA 1-15P (e.g. two vertical blade unpolarized) AC cable.
مشخصات سایر قطعات
Intelligent Battery controller board:
SATA-style connector to route power and control signals to the main board
Works with battery packs used by most RC enthusiasts
Pre-populated with 3S1P balancing tap connector
Cheap and easy to buy
User can "pick their capacity" -- the battery life isn't fixed by design, it's up to the user
Classic Molex disk connector for battery connector
Requires adapter cable to the RC battery pack
Fast-charge capability
Rates in excess of 4A
Charge a 45Wh 3S1P pack in ~1 hour
Active cell balancing
Learns your battery pack
Over a few charge/discharge cycles, the controller determines the actual capacity of the pack
Tracks capacity degradation over time
Optimizes charging to reduce wear and tear on packs
Computes an accurate estimate of remaining battery capacity
Statistics reporting
SMBus standard power interface
Stats such as remaining capacity, charging rate, current discharge rate, voltage, etc. available
STM32 master controller
Runs ChibiOS
Enables autonomous operation when CPU board is powered off
Reprogrammable by host CPU, but requires a physical button press to enable programming, as a guard against surreptitious malware insertion
Has DAC output to drive an analog panel meter
240 GiB SSD:
SATA-II interface (3Gbps)
Intel 530 series or equivalent (SanDisk drive in the photos is a throw-away for our dev purposes only, we would not subject end users to such a drive)
Full desktop Debian firmware load
Battery pack:
3000mAh 3-cell lithium battery pack
3-4 hours battery life depending on backlight level
May improve with firmware tuning of power management functions (measurements done with no CPU throttling, all peripherals powered on even if unused)
Manufactured by Turnigy and shipped separately, installed by user
User can swap in their own battery pack
Cable adapter from Molex to in-line 4mm bullet connector provided
