Apparently the Panda is FCC-certified. I searched the questions for FCC and got a hit.

Re: In search of reliable FCC-certified USB Wi-Fi adapter with removable antenna
When I checked the page for the Panda adapter I also found this: https://www.amazon.com/gp/aw/d/B071Y6Y83W/ref=psdcmw_13983791_t1_B00JDVRCI0 Bit higher than budget but I will manage.

I'm needing to include a second Wi-Fi adapter with a Zero W in a product I am building. Any recommendations? Must haves: Reliable, I don't want a lot of returns FCC-certified Removable antenna. I will mount the antenna externally. Relatively low-cost, around $15 in bulk or less would be ideal, but I...

Re: Zero W with extra USB Wi-Fi adapter; One static, one DHCP client
Solved. Helps to use the correct SSID in wpa_supplicant.conf
Otherwise, that configuration is correct.

[SOLVED] Zero W with extra USB Wi-Fi adapter; One static, one DHCP client
How do I configure Raspbian Stretch Lite on my Zero W with a second USB Wi-Fi adapter? The built-in adapter (wlan0) must have a fixed IP (192.168.4.1) serving hostapd and dnsmasq. The second (wlan1) uses a standard DHCP client. How would I configure this? I've managed to work out setting up wlan0 wi...

Re: View camera on a phone without opening the firewall
Not yet. Been super busy with the rest of the product, plus life in general. Nothing has changed from the plan in the first post though; that’s how I excpect it to work, with ffmpeg and RTMP. But it may be a while before I can test it.

Re: host camera module mjpeg output on remote server?
A down side of SSH port forwarding: If someone were to hack the web server (not unthinkable) they would then be able to reach into your home network. They would have to then hack the IP camera but that's definitely not difficult these days; many of them don't get new firmwares. Typically they have a...

Re: Ok to have a 3m shielded serial cable?
1. D’oh! Will tweak that. Copied this from a Digikey article called Protecting Inputs in Digital Electronics . But that has more to do with GPIOs. 2. 3.3V and it will have its own power source. This should low-pass anything below 36 kHz if I'm figuring this correctly. https://i.imgur.com/hKuvIeB.png

Re: Protecting GPIOs from ESD
Yes, they are 5V rated rather than 3V3 - but that's not really the issue with ESD: the SoC in the Pi will have its own protection structures which can tolerate short-duration overvoltage (and even modest ESD events), what you are after here is that when a serious ESD event occurs (1000s of volts!) ...
