The REES52 Promise
The REES52 Promise
We want you to build, not worry. Here is exactly what happens if something goes wrong with your order.
Dead on arrival or defective? We replace it.
If your item is dead on arrival or has a manufacturing defect, tell us within 7 days of delivery. Email support@rees52.com with your order number and a short video or a couple of photos showing the problem. Our team will get back to you within 24 hours and arrange a free pickup from your doorstep - you never pay return shipping for a defective item. Once we verify the issue, your replacement ships out right away. If the item is out of stock, you get a full refund instead.
Refunds, with real timelines.
- Approved refunds go back to your original payment method within 6-7 working days.
- Missing item in your package? Tell us within 7 days with photos of what arrived and the parcel label. Once confirmed, the refund for the missing item reaches you in 2-3 working days - or we ship the missing piece free, your choice.
- Every refund comes with a reference number by email or WhatsApp, so you can track it with your bank instead of chasing us.
Wrong item or not as described?
Email us your order number and a photo of what you received. We arrange the return pickup, and ship the correct item as soon as the return is on its way. Prefer your money back instead? That is fine too - full refund, same 6-7 working day timeline.
About lead times on some products.
A few items on rees52.com are sourced from our overseas partner warehouses and are not sitting on our shelf. Those products show a lead time of about 20-25 working days on the product page, before you pay. If you order one, we keep you posted as it moves. Changed your mind while waiting? You can cancel any time before dispatch and get a full refund within 6-7 working days. No cancellation fee, no questions.

Description:
CJMCU-219 Power Supply Monitoring Module with the I2C interface of zero drift and bi-directional current/power monitoring and control integrated circuit (IC). CJMCU-219 Power Supply Monitoring Module has the industry’s highest precision and the small size, not only monitors the pressure drop on the shunt resistor, sensing shunt power supply voltage, but at the same time also calculates the power. This CJMCU-219 Power Supply Monitoring Module will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this CJMCU-219 Power Supply Monitoring Module to measure both the high side voltage and DC draw over I2C with 1% precision. The device adopts the SOT23 packaging, but the server, notebook computer, power supply, battery management digital electric vehicle and telecommunication equipment measuring flu provide a small low-cost solution. A precision amplifier measures the voltage across the 0.1, 1% sense resistor.
Since the amplifier's maximum input difference is ±320mV this means it can measure up to ±3.2 Amps. With the internal 12-bit ADC, the resolution at ±3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is ±400mA and the resolution is 0.1mA. Advanced hackers can remove the 0.1-ohm current sense resistor and replace it with their own to change the range (say 0.01 ohm to measure up to 32 Amps with a resolution of 8mA). INA219-40 c to + 85 c temperature range and can realize the maximum error of 1% accuracy, a maximum offset of 100 μV. The advantage of the high precision of the product in combination with 12 resolution, can help clients as much as possible, reduce the pressure drop on the shunt resistor, which can minimize the power loss and power consumption, and save board space. The CJMCU-219 Power Supply Monitoring Module epic of 26 bus voltage range of 0 V to + V.
Specification:
- Operating Voltage: 3 ~ 5.5V DC
- Accuracy: ±0.5%
- Operating Temperature Range: -40 to 85°C
Features:
- CJMCU-219 Power Supply Monitoring Module is programmable calibration register can be read in units of ampere direct current, and read the power in watts.
- Up to 128 samples can be averaged to achieve filtering in noisy environments.
- CJMCU-219 Power Supply Monitoring Module I2C interface has a timeout setting, not only to prevent bus lock but also to provide high-speed mode, to meet the communication requirements of up to 3.4 MHz.
- All properties INA219 are software programmable to support.
- CJMCU-219 Power Supply Monitoring Module is a single power supply, with an operating voltage of between +3.0 to + 5.5V.
Package Included:
1 x CJMCU-219 Power Supply Monitoring Module INA219 I2C Interface No Drift Bi-directional Current / Power Supply Monitoring Module
