4in1 PCB for the Chorus RF Laptimer by Andrey Voroshkov https://github.com/voroshkov/Chorus-RF-Laptimer
https://www.youtube.com/watch?v=avLRJ5z0UP4
- PCB for 4 Nodes (4 Pilots)
- easy extendable via JST XH cable (8 Pilots)
- 5V stepdown for Arduinos
- adjustable stepdown for RX Modules (use 3.5V to keep temperature low)
- 92 x 92mm mounting holes
- XT60 PowerIn
- 5V USB PowerIn (if you want to use a powerbank)
- stacked hardware - can be changed in seconds
- Buzzer Port to connect one Buzzer per Node
22.05.2018 - v3.1 beta released DOWNLOAD
- inital release
- i did not tested this PCB. To V3.0 i just added the Diodes and did cleaned it up a bit. V3.0 worked so far. Please report any issues!
You can use less than 4 nodes. All you have to do, is to bridge TX/RX (see silkscreen) of the unused nodes. Always use at least "Node1" because the voltage measurement is connected to this node.
If you want to power the unit via 5 V USB, please remove stepdown marked as "Arduino" and bridge IN and OUT of it to pass the power from the USB to the Arduios.
If you plan to track more than 4 pilots at the same time, connect just connect two or more PCBs together.
- Please always set the Loopback Jumper to the first PCB.
- Connect the next PCB via 6Pin JST cable
- On the first PCB, bridge MV
- On following PCBs please bridge GM
- WiFi/Bluetooth Module always connects to the last PCB.
