GPS Breakout - ZOE-M8Q (Qwiic)
... show moreThe SparkFun ZOE-M8Q GPS Breakout is a high accuracy, miniaturized, GPS board that is perfect for applications that don't possess a lot of space. The on-board ZOE-M8Q is a 72-channel GNSS receiver, meaning it can receive signals from the GPS, GLONASS, BeiDou, and Galileo constellations. This increases precision and decreases lock time and thanks to the onboard rechargable battery you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.1 Comment

FM_Transmitter
... show moreThis is one of the simplest FM transmitters that can be built. It does not require any tuning, and transmit frequency is crystal locked to 90MHz. It eliminates frequency drift common to LC-based FM transmitters. This design is best suited for broadcasting voice or music up to a distance of fifty metres depending on the antenna used.17 Comments

The NEO-M9N module is a 92-channel u-blox M9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations witn ~1.5 meter accuracy. This breakout supports concurrent reception of four GNSS. This maximizes position accuracy in challenging conditions, increasing precision and decreases lock time; and thanks to the onboard rechargeable battery, you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports.

... show moreSmartDeskPet v1.0 Shield Stage 1 status:- Goal: 5V input -> dual AMS1117-3.3 rails (+3V3_MCU and +3V3_WIFI) with common GND.
- Note: Keep power nets explicitly named (avoid unnamed nets) to keep ERC happy. Stage 1 completion checklist:
- Mark J1 Pin_1 (+5V) as a Power Output pin to satisfy ERC power-driver checks.
- Verify all GND symbols/returns are on the same GND net.
- Keep +5V_SERVO isolated from the main +5V net (only share GND). Stage 2 preparation notes (MPN/LCSC + layout constraints):
- MPN/LCSC targets to define before Stage 2 exit:
- AMS1117-3.3 (SOT-223): set exact MPN and (optionally) LCSC PN for both U1 and U2.
- 100nF capacitor (0603): set MPN/LCSC for all 0603 100nF decouplers.
- 4.7k resistor (0603): set MPN/LCSC for I2C pull-ups R1 and R2.
- 1000uF bulk capacitor (radial): set MPN/LCSC for C7 (CP_Radial_D10.0mm_P5.00mm).
- DC005 power jack/regulator input: select exact DC005 footprint + MPN/LCSC (if used).
- 2.54mm headers/sockets: set MPN/LCSC for H1, H2, J1, J3, J4, J5, P3, P4, P5, and J2.
- ESP-01S antenna keepout:
- Reserve a copper keepout under and in front of the ESP-01S onboard antenna.
- No copper pours/traces/components in the antenna region (top and bottom) per module guidelines.
- H1/H2 header spacing:
- Maintain 1000 mil spacing between H1 and H2 header centerlines (shield mechanical requirement).
- Silkscreen placeholders:
- Add silkscreen labels for: 5V IN, GND, +3V3_MCU, +3V3_WIFI, SERVO1, SERVO2, I2C SDA/SCL, DHT11, ASRPRO UART2, ESP-01S UART3.
- Add placeholder text for: MPN, LCSC, board revision, and date code. Stage 3 layout constraints (placement and routing guidance):
- Connector placement strategy:
- Place H1 and H2 first to lock the shield mechanical interface; enforce 1000 mil spacing.
- Place J1 and any DC005 input at the board edge for easy access.
- Designated power area planning:
- Group U1, U2, and C7 near the 5V entry point; keep high-current 5V and regulator loops short.
- Use wide copper for +5V and any servo supply; stitch GND around power section.
- Antenna keepout boundaries:
- Place J2 (ESP-01S socket) at a board edge with the antenna facing outward.
- Enforce a top-and-bottom copper keepout in the antenna region; keep noisy power traces away.
