我 8051U 回来了
我觉得上面第一张图8051字太大了，不协调
好强大的STC851U，一直在等 ，在公司期待一个这么强大的实验箱，还没有过STC的实验箱，好期待
不但是听歌神器，还是。。。

我 8051U 回来了
第二款丝印好看，精致，显得更正式，第一款比较细，虽然大但是看起来还不如第二个清晰。

我 8051U 回来了
建议下面的，字高 线宽 比 不能太大（字高线宽就要粗，字矮可以细，这种0线宽的建议矮字）
{:4_174:}{:4_174:}{:4_174:}{:4_174:}期待能有个试验箱
丝印下面的好

My big 8051U is back
The IC's silkscreen marking should directly reflect the orderable part codes.
That makes the QFP44/QFP48 better than the DIP40.
eg If the orderable part code is STC8051U-32K64-QFP48
The silkscreen should split that part code into two lines -
either
STC8051U-
34K64-QFP48
or
STC8051U
-34K64-QFP48
The TFPU@108M should not be the first marking, as that will be seen as a part code by many people.
It can go under the part, in smaller font, like this :
STC8051U
-34K64-QFP48
TFPU@108M
DateCodes
The heading mentions STC8051USB, so also ok is this part code / label
STC8051USB-32K64-QFP48
STC8051USB
-34K64-QFP48
TFPU@108M
DateCodes
Addit: I see most other STC parts have MHz included in the order part code.
Should that MHz info also be included for STC8051U ?

能否与时俱进上触摸屏，数码管这些用处少了很多能否与时俱进上触摸屏，数码管这些用处少了很多
===最近4年的大学计划实验箱，都是支持触摸TFT彩屏的
支持支持，等了一年终于要到啦，支持
