Acquisition
About the Acquisition PCB
Acquisition is an open source PCB design by Pinheirogustavo, published on GitHub. It is a 2-layer board measuring 90 × 100 mm, with 29 components from 19 distinct parts.
Other key parts include the BLUEPILL_STM32F103C, LM2596S-5 and LM1117T-3.3. By type, the board carries 15 connectors, 6 ICs, 4 capacitors, 2 inductors, 1 diode and 1 resistor.
From the project
Esta versão suporta até 4 módulos stm32 bluepill. Onde é possível demodular 4 ou 8 canais externos em cada módulo.
Esta versão suporta até 4 módulos stm32 bluepill. Onde é possível demodular 4 ou 8 canais externos em cada módulo.
A alimentação de cada módulo é "dedicada". Isto é, há um regulador de tensão StepDown implementado na placa que fornece a tensão de 5V (5Vstepdown), que é regulada a 3.3V (3,3Vstep) que é empregada na alimentação dos módulos. Em resumo os estágios são:

Acquisition: common questions
How big is the Acquisition PCB?
The Acquisition measures 90 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Acquisition?
29 components, from 19 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 Acquisition design files?
From the Pinheirogustavo/PCB_projects 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 Acquisition design in my own project?
The repository has no license, so all rights stay with Pinheirogustavo. Use it as a reference, and ask the author before reusing the design.
