- Get 10 PCBs for just $2 & $7 for a SMT Stencil at jlcpcb.com/DYE

APA102-2020 on AliExpress: www.aliexpress.com/item/10-30...
For full disclosure: I asked JLCPCB to sponser this video. They were kind enough to also provide me a stencil. The quality of their PCBs and the communication with them has always been great, I wouldn't recommend them otherwise!
Buy a board on Tindie (soon): www.tindie.com/stores/spacehuhn/
You can buy one of the DSTIKE boards on Tindie and AliExpress to support me and the channel :)

Or buy somethin on Amazon over these affiliate links (it doesn't cost you anything extra, but I get a commision):

Very interesting video :) sometime i wanna try to do some small matrix board with these tiny 2020 packages :D Or some RGB-Strip-Sticks with ultra tiny space between the leds ^^
But first ill have to check if im even able to solder these XD
Awesome tutorial. Couple of questions if I may. Whats the logic level of the Data Pin for the LEDs. 3.3V or 5V? Also could you change the frequency of the clock pin? What I mean by that. Is it possible? Final question are you supplying the power for the LED's with your board or do you use a external power source?
You can order a much more appropriate sized stenicl but selecting "custom size" from JLC PCB.
I should have paid more attention to the ordering page myself...
On the other hand, it was more fun with cutting it and everything :D
spacehuhn I'm sure the person who made the stencil also had a pretty good laugh. (Insert "It's so tiny" gif)
hey bro, for more multi-size, multi-shaped boards, have a try PCBWay,
@@spacehuhn Next time try panelizing them so you can stencil a whole bunch at once! Much, much easier.
You can get them to panelise the boards.... get at least 5x6 = 30 of those on one board... so you get 300 snap-off-able lil boards for your $2
This is great advice for my upcoming project
Can I ask you some questions about the LED chip please? I received 10 of them yesterday.
1. Do they come on a strip? I have never seen one advertised. Have you?
2. They have 8 pads on the underside. - the 6 user pads, and two others , marked A and B on my pad diagram below. What are A and B?
1 : SDI A SDO : 6
2 : CKI CKO : 5
3: GND B VCC : 4
The reason I ask is that I want to make a strip on a single-sided board, with one power rail above the chips and one below, and as VCC and GND are on the same end of the chip, I will have to take a trace underneath the chip, and it is likely to make contact with A or B. Are they connected to anything internal to the chip?
3. What is the maximum data rate? The datasheet mentions an "oscillator frequency" min: 800kHz, Max : 1200kHz - but -"oscillator"? The only one I can think of is the PWM oscillator, but the user can't change it. If it is referring to the data rate, then I can't use the chips anyway at that throughput, but another user said that he got 40 MHz through the 5050's. Do you know what it is for the 2020's?
check in indian sites like ebay.in or flipkart, amazon.in cause it is cheap here
NS107S Pixel LED:
PWM refresh rate >26kHz
, Transfer speed is >30MHz.
And NS107S is much better than APA102.
NS107S-5050, $**/K
NS107S-3535, $***/K
NS107S-2020, $***/K.
I just got some, they are soooo tiny
I just got some too - but a year after you got yours. Did you have any success?
I just got 10 to play with, but my intention is to use 220 of them in a strip, with 1 LED every 2.5 mm. Did you manage to solder them?
Did you not need resistors
first :)
no
YES
@@spacehuhn good job roasting m8
@@spacehuhn bro I have a doubt
Kindly read this I bought a nodemcu kit on Amazon
°°
"Preprogrammed with nodemcu firmware"""""
10 Gpio, every gpio can be pwm, i2c, 1-wire, fcc certified wi-fi module, pcb antenna
Usb-ttl included, plugandplay
Exclusive tutorials for esp8266 - roboindia
So they gave preprogrammed so does it come flashed?
Ps I'm a nub at programming...
Sry for shit english
Due to google autocorrect
