TRANSMITTER SMD
About the TRANSMITTER SMD PCB
TRANSMITTER SMD is an open source AVR/Arduino PCB design by vul-os, published on GitHub under the MIT license. It is a 2-layer board measuring 39.4 × 54.3 mm, with 12 components from 10 distinct parts.
Its main chip is the ATtiny412-SS, from the AVR/Arduino family. Other key parts include the INA181, DRV8871DDA and L78L05_SOT89. By type, the board carries 5 ICs, 3 connectors, 3 diodes and 1 transistor.
It belongs with the sensors, robotics & motion and iot & wireless designs in this gallery.
From the project
Zana — open-hardware for the physical world: robot mowers, security & cleaning bots, sensor nodes and cameras that plug into any control plane. Build them yourself. FreeCAD + KiCad.
Open-hardware design for an autonomous robot mower with inductive charging — the first Zana device.
Originally prototyped as "mowbot"; preserved here as the reference design.
- mowbot.FCStd … mowbot4.FCStd — main body / chassis, four iterations. mowbot4 is the latest; build from that one. - shaft.FCStd / .3mf, coupler.FCStd, gt2-pulley.FCStd — drivetrain: shafts, couplers, pulley. - alimunumcoupler* — aluminium coupler variant (STL + FreeCAD). alcoup.dxf / .svg / .pdf are its 2D cutting profiles. - castorfitting, socket.FCStd, plate.dxf — castor mount, a connector/socket part, and the…

TRANSMITTER SMD: common questions
What microcontroller does the TRANSMITTER SMD use?
The TRANSMITTER SMD is built around the ATtiny412-SS, from the AVR/Arduino family.
How big is the TRANSMITTER SMD PCB?
The TRANSMITTER SMD measures 39.4 × 54.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the TRANSMITTER SMD?
12 components, from 10 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the TRANSMITTER SMD design files?
From the vul-os/zana repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the TRANSMITTER SMD design in my own project?
Yes, under the terms of its MIT license, which vul-os chose for the repository.
Can I test firmware for the TRANSMITTER SMD without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
