Because buying Pi 3A+ plus official Raspberry Pi A+ case allowed for free shipping, with cost less than the cost of Pi 3A+ alone plus shipping, I ordered both.
After installing Raspberry Pi Stretch and configuring camera/ssh/i2c, raspivid works fine.
I have not seen thermal warning sign displayed on HDMI monitor yet.
Is running Pi 3A+ with camera, USB wireless keyboard dongle, HDMI monitor connected and official Raspberry power supply expected to not produce thermal issues with closed case?
There are 4 screw mounts at bottom of the case, but neither Pi 3A+ nor official A+ case came with screws. Is that normal?
The SD-card on one side and USB slot on the other side seem to fixate the Pi 3A+ in the case in such a way, that at least two screw mounts are inside the Pi 3A+ mounting holes. That seems to be firm enough when using the case normally. Later, when I will add the case on new T101 caterpillar robot platform I will use 4 screws to fixate the Pi 3A+ firmly to the case, that will be fixated on robot platform.
Why are there no free slots for camera and/or display ports?
That is not a big problem, my Dremel simply added the needed camera cable slot:
to /boot/config.txt and rebooted. Now HDMI resolution matches what the (old) HDMI monitor can do.
Code: Select all
hdmi_group=2 # DMT hdmi_mode=39 # 1360x768 60Hz
I played youtube videos in Chromium webbrowser (with audio to HDMI monitor) for quite some time now.
With youtube fullscreen mode, the display is a bit pixelized, but no video nor audio dropouts.
Still no thermal warning sign on HDMI monitor ...
After more than an hour of playing fullscreen youtube as described, "vcgencmd measure_temp" reports temperatures between 61° and 63°. Total CPU utilization of the 4 cores (3 chromium-browse processes, Xorg, ...) is around 23%. Measured arm frequency is 1200000000 (configured arm_freq is 1400, gpu_freq is 300). Seems to be safe temperature wise to run 3A+ long time in case ...
