2 layers3.2 × 105.5 mm
MA735 encoder board
techy-robot/CACKLE-nanoSPI-MA735_magnetic_encoder
This is a super compact SPI magnetic encoder, with the flex cable being 2.4mm wide and 100mm long, and the tip around 5.6mm diameter. It is quite simple, and supports on shaft or side-shaft mounting with correction.

2 layers45 × 5 mm
End Cap
techy-robot/CACKLE-Passive-Endcap
The only purpose of this is to provide a nice end to the chain. It has rounded corners like the PSU at the beginning, and it also has a 120ohm termination resistor for the RS485 bus.

2s 40A PSU and charger
techy-robot/CACKLE-PSU-2s_40A_PSU_and_charger
This is a rather complex power supply unit. It supports USB-C Power Delivery at 9volt 2 amps, and can charge a 2 cell lipo battery. It can pump out 40 amps if the battery supports the current.
115 parts
2 layers30 × 20 mm
USB only 2A PSU one side
techy-robot/CACKLE-PSU-USB_2A_PSU_1side
The main ICs are an mcu, and a 5v 2a switching regulator. The system can theoretically handle 20 volt spikes, but this is mostly meant for 5v output on one side only.
