RP2040 5kg Scale Electronics Kit with HX711 & OLED Display

Develop your own digital weighing project with the RP2040 5kg Scale Electronics Kit. It pairs an RP2040 Zero board with pre-soldered headers, a 5kg load cell and HX711 amplifier, and a 0.96-inch blue SSD1306 I2C OLED. Your firmware reads the amplified load-cell signal and can show experimental weight readings on the display. A 400-point breadboard and 10cm jumper set support the electronics, while you design the mechanical mounting, wiring and software. Calibration with a known weight is required; the load cell's 5kg rating does not establish the accuracy of the finished scale.

Bundle value: Purchased separately, the included component variants total $33.61. This kit is $27.99, saving $5.62.

• 1 × RP2040 Zero board with pre-soldered headers
• 1 × 5kg load-cell kit with HX711 amplifier
• 1 × 0.96-inch blue SSD1306 I2C OLED display
• 1 × 400-point solderless breadboard
• 1 × 120-piece, 10cm jumper wire set: male–male, male–female and female–female

Mechanical assembly, wiring, firmware and calibration with a known weight are required before use. A USB-C data cable, computer, power source, calibration weight and enclosure are not included. The 5kg rating describes the load cell; finished scale accuracy depends on your mounting, calibration and software.
