Downloading Gerbers/PCBA files for assembly service

PCBA files are generated in the build artifacts on each commit. Download the build artifacts from the latest commit under the Actions tab. Upload the default gerber zip to JLCPCB, and use default.csv for the BOM file + default.pos.csv for the CPL file

Requirements

atopile

rust, espup, espflash

Directory

Ato builds

Ato builds listed in ato.yaml

Veramonitor.ato is the main build. The final PCB is build from this, and the corresponding kicad project is in elec/layouts/default/veramonitor.kicad_pro

kailh-sw.ato contains the keyswitch+neopixel module. kicad files are located in elec/layouts/kailh-sw

MAX98357AETE_plus_T.ato contains the ClassDAmp module

TESTING IN PROGRESS:

Wavshare 1.8in LCD Module with ST7735 Controller

module TFTDisplay in elec/src _1_peroid_8INCH_space_MODULE.ato LCSC_ID = C359940

SPI Pin mapping (elec/src/veramonitor.ato, line 67):

    lcd.spi.mosi ~ micro.io13; lcd.spi.sck ~ micro.io12; lcd.spi.cs ~ micro.io11; lcd.spi.dc ~ micro.io10; lcd.spi.reset ~ micro.io9; lcd.spi.backlightEN ~ micro.io46

MAX98357 Amp + Speaker

Uses MAX98357 (LCSC ID = C910544) 3W Class D amplifier IC + KLJ-1304T Speaker (LCSC_ID = C18186315). ESP32-S3 sends digital audio data to MAX98357 via I2S.

I2S Pin Mapping (veramonitor.ato, line 73):

    amp.LRCLK ~ micro.io8; amp.BCLK ~ micro.io18; amp.DIN ~ micro.io17

Test SK6805 neopixels

WS2812B style protocol. Defined in elec/src/sk6805-ec20/elec/src/sk6805-ec20.ato

Neopixels invoked and configured in each KailhSW module

Neopixel Pin Maping (veramonitor.ato, line 70):

    micro.io16 ~ sw1.DIN; sw1.DOUT ~ sw2.DIN; sw2.DOUT ~ sw3.DIN; sw3.DOUT ~ sw4.DIN; sw4.DOUT ~ sw5.DIN; sw5.DOUT ~ sw6.DIN

CPG1511F01S05 Kailh Switches

Accomodates standard keycaps LCSC_ID: C400225 Kail module configured in elec/src/kailh-sw.ato.

Active low. Pin mappings:

    micro.io14 ~ sw1.KEY; micro.io21 ~ sw2.KEY; micro.io47 ~ sw3.KEY; micro.io48 ~ sw4.KEY; micro.io45 ~ sw5.KEY; micro.io35 ~ sw6.KEY

SW1 ~ GPIO14; SW2 ~ GPIO21; SW3 ~ GPIO47; SW4 ~ GPIO48; GPIO45 ~ SW5; SW6 ~ GPIO35

SPH0641LU4h1 MEMS microphone

LCSC_ID = C2879853

PDM Pin Mappings:

    pdm.pdm_sel ~ mic.SELECT; pdm.pdm_sel ~ micro.io3
    pdm.pdm_clk ~ mic.CLOCK; pdm.pdm_clk ~ micro.io5
    pdm.pdm_data ~ mic.DATA; pdm.pdm_data ~ micro.io4

To Do

1: Verify basic functionality

2: Finish rust firmware

3: Home assistant integration

4: 3D printed enclosure/wall panel mount
