硬件清单如下：
1. 3G/HSDPA modem, minimum download speed 3.6Mbit/s, USB or UART interface, either module or chip solution (QCA)
2. WiFi module, chip or Wifi SoC - QCA4004 based module, or QCA4004 chip. Any reliable and cheap WiFi is acceptable. AR9331 or QCA9556 solution is acceptable too.
3. 4GBytes (32Gbit) eMMC memory.
4. Cortex M4 compatibile MCU to manage (1) and (2) and to decode MP3 audio, MCU with integrated AUDIO codec is preferred.
5. Power supply IC for voltages required by 1, 2, 3, 4 - linear regulators are acceptable.

po主，你是要购买你说的器件（WiFi/3G芯片,DDR...)，还是已经设计好产品方案，只需要SMT贴装+组装？
如果只需要贴装+组装，我们公司可以做。 公司地点：湖北荆州； SMT设备：松下602； 可以用微信联系我：neal-zhang; 我们可以根据你的电路图+BOM对加工报价。 |
