Its main chip is the ESP32-WROOM-32E, from the ESP32 family. Other key parts include the Gabellichtschranke, AMS1117-3.3 and CP2102N-A01-GQFN28. By type, the board carries 34 resistors, 26 capacitors, 20 diodes, 12 connectors, 9 inductors and 6 ICs.

From the project

Damper Control for ventilation exhaust system in realraum

wird geschalten mit: Neuhold SSR Typ ZG3NC-240B hängt im Phasenleiter. Datasheet: http://www.ndu.cl/pdf/0509040FT.pdf Schaltleistung: 40A mit eingebautem Snubber. bei induktiven Lasten: 40% Strom der 40A sind ok --> passt für unseren Motor uns seiner Startlastspitzen.

SSR zieht laut Datenblatt maximal 40mA laut Tests: müsste mit teensy2 pin als Senke fast ohne Transistorschalter direkt zu schalten möglich sein. da atmega32u4 laut datenblatt 20mA permanent per IO senken kann solange die Summe einer im Datenblatt definierten Gruppe von Ports nicht 100mA überschreitet.

Luefterklappensteuerung: common questions

What microcontroller does the Luefterklappensteuerung use?

The Luefterklappensteuerung is built around the ESP32-WROOM-32E, from the ESP32 family.

How big is the Luefterklappensteuerung PCB?

The Luefterklappensteuerung measures 80 × 87.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Luefterklappensteuerung?

115 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the Luefterklappensteuerung design files?

From the realraum/luefterklappensteuerung repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Luefterklappensteuerung design in my own project?

The repository has no license, so all rights stay with realraum. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Luefterklappensteuerung without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
