Welcome to the Pitanga project, my very first PCB design endeavor using KiCad 7.0. This project served as a significant learning experience, allowing me to delve into the world of PCB design, Raspberry Pi extension hats, and various hardware components.
-
PCB Manufacturing:
- Initiated with the ordering of the first PCBs (0.01 and 1.0 versions) from PCBWay, marking the beginning of the project.
- Subsequently transitioned to JLCPCB for future revisions, benefiting from their commendable PCB quality and competitive pricing.
-
Evolution of Design:
- Progressed from a 2-layer PCB in version 0.01 to a more complex 4-layer design in version 1.0.
- Experimented with a DC-DC converter in version 2.0, only to return to the simplicity of 2 layers in version 2.1.
-
Technological Exploration:
- Introduced the utilization of the HT16K33 driver and various LED 5x7 displays.
- Integrated a set of 5 tactile buttons into the design, establishing a connection with the HT16K33 driver.
- Expanded the project to include diverse LED displays, ranging from MAN2 to the latest respins of Til-305, encompassing even USSR variants.
-
Supported Displays:
- The Pitanga supports a variety of displays, including but not limited to:
- Monsanto MAN 2
- IEE - LRT1704R
- DIALCO 745-0005
- LTEON LTP-305
- TI Til-305
- ALS340A
- ALS340A1
- 3LS340
- 3LS363
- AL104
- The Pitanga supports a variety of displays, including but not limited to:
The Pitanga project encapsulates my journey in PCB design in KiCad 7.0. Each version of the board represents a step forward in understanding, incorporating new features, and refining the overall design.
