IOT123 BRICKS yog chav DIY modular uas tuaj yeem sib xyaw nrog lwm IOT123 BRICKS, txhawm rau ntxiv kev ua haujlwm rau ntawm qhov chaw lossis hnav tau. Lawv tau ua raws li lub xwmfab nti, ob-tog protoboards nrog sib cuam tshuam los ntawm qhov.
Txawm hais tias cov lus qhia cuam tshuam nrog ib nrab kev ruaj khov ntawm BRICKS, tus txiv neej tus pin txuas nrog piav qhia ntawm no tuaj yeem hloov pauv rau ib khub (txiv neej ntawm cov neeg siv khoom/poj niam ntawm tus muab kev pabcuam) ntawm lub taub hau pins kom yooj yim sib dhos. Tsis tas li daim ntawv cog lus tus pin (txoj haujlwm thiab lub ntsiab lus ntawm kev txuas tus pin) cuam tshuam nrog ATTINY85 NRF24L01 BRICKS, tab sis tuaj yeem hloov kho kom haum rau lwm qhov IOT123 BRICK daim ntawv cog lus.
Lub hwj chim tawm tswv yim cia siab tias 5V DC los ntawm MicroUSB lub qhov (socket), uas yog smoothed/ntxuav nrog cov capacitors thiab tso tawm raws li 3.3V nrog tus tswj hwm AMS1117. Kev hloov pauv tau sib xyaw ntawm 2 PCBs thiab +ve/GND tus pin tau nthuav tawm rau kev siv los ntawm lwm qhov BRICKS.

- Hauv qab qhov muag YELLOW1, BLACK3, YELLOW2, thiab YELLOW3. Khoov lub capacitor hla tom qab SPDT hloov; xyuas kom cov hlau lead tsis txhob kov lwm cov ntaub qhwv.
- Nyob rau sab saum toj, xov a -ve ua rau ntawm 10uF tantalum capacitor rau YELLOW6 tom qab ntawd mus rau YELLOW7 hauv qab.
- Nyob rau sab saum toj, xov lwm +ve ua rau ntawm 10uF tantalum capacitor rau hauv YELLOW8 tom qab ntawd mus rau YELLOW9 hauv qab. Lub tshuab hluav taws xob no yuav tsum nteg tiaj kom ntseeg tau tias muaj kev ua si txaus hauv cov hlau lead. Hauv qab qhov muag YELLOW6, YELLOW7, YELLOW8, thiab YELLOW9. Khoov lub capacitor hla mus rau SPDT hloov; xyuas kom cov hlau lead tsis txhob kov lwm cov ntaub qhwv.
