新人第一帖,发个S3的核心板(AXP209+S3)

一个AXP209和一个S3,存储和WiFi都没有……

PE部分引出,右侧FPC是全部PD,左侧FPC是全部AUDIO相关,其余的引脚都在半孔上。

欢迎老前辈点评

(BGA焊到头秃

我翻了一下 axp209 手册:

2 路同步降压转换器 (DC-DC)

  1. DC-DC2:可在 0.7-2.275V之间调节, 25mV/step, 驱动能力 1.6A,  支持 VRC

  2. DC-DC3:可在 0.7-3.5V之间调节, 25mV/step, 驱动能力 1.2A

5 路线性稳压器 (LDO)

  1. LDO1:30mA,始终有效

  2. LDO2: 低噪声 LDO, 1.8V~3.3V可调节,100mV/step, 驱动能力 200mA

  3. LDO3:0.7-3.5V可调节, 25mV/step,  驱动能力 200mA

  4. LDO4: 低噪声 LDO, 1.8V~3.3V可调节,100mV/step, 驱动能力 200mA

  5. LDO5:低噪声 LDO, 1.8-3.3V可调节, 100mV/step, 驱动能力 50mA

这输出可调范围这么大, 那上电的时候到底是多少v呢?

SD卡都没有哈哈,公司用这个核心板的场景可能还挺不一致的,有用SPI Flash的,有用那种128M的贴片NAND的,有用EMMC的,反正用啥存储底板说了算,三路SDIO都引出了。

手册里有写默认输出值,可以按照寄存器默认值计算的。
但注意买的芯片一定是非定制芯片,不然没准输出多少V的电压。
