ESP8266 test programmer

The module allows for quick debugging, eliminating the need for soldering and improving fault tolerance. It features an automatic download circuit, a CH340C to serial port chip with all pins exposed, and a built-in OLED interface for easy programming and debugging. This work references similar projects from several other developers.

The description states
a desire for a full-featured ESP8266 programmer, but not a preference for the ones available online. The desired features include a Type-C interface, a pleasing design, a rich set of interfaces, and a user-friendly programming experience. Based on the following examples, a custom programmer was created, essentially a collection of examples :       2
*
      4*2.54mm female headers, an IIC screen interface,
      and
      a single pin header on the back (they seem bulky with double rows of female headers on both sides). Automatic programming is referenced in the ESP8266 programming rack (JLCPCB EDA Open Source Hardware Platform (oshwhub.com) ). Thanks to all the open-source contributors! The test ring in the effect diagram was an idea proposed by luoxing. It uses pure copper pins. For the size 0 pin, the non-pin side needs to be cut off along the top. Then, during component insertion, insert the pointed end into the round hole. For positions R1/R2, since there are no 1k resistors, a lump of solder is used for connection; this does not affect functionality. For aesthetics, two LED pins could be added. The board mounting order is: pins, 2*4 female headers, 1*4 female headers, then pin headers.

A 5V 40A DC-DC module based on PW22ASAB

This DC-DC converter uses two PW22ASAB modules. It is primarily designed for multi-bay NAS enclosures, providing both 12V and 5V power to the hard drives, addressing the issue of insufficient 5V power supply from standard enclosure power lines. Suitable for setups with eight or more hard drives.

Function Introduction:
Two PW22ASAB connectors can provide a total of up to 40A of 5V power supply, fully meeting the needs of multi-bay hard drives. Recommended for use in environments with 8-16 drives (8-bay tested).
The layout
uses a 4-layer board. The top CN1 and CN3 are 12V input terminals, with the same wiring sequence as the 8-pin power cable for graphics cards.
Considering different usage environments, the output port wiring sequence needs to be carefully checked.
The bottom CN4, CN6, and CN5 are output ports, consisting of a two-pin 12V direct output, a two-pin 5V output, and a 4-pin GND
input. The CPU 8-pin 5569 connector (straight-through, solid pin)
and output ports are CPU 8-pin 5569 connectors (angled, solid pin).
Again, the output port wiring sequence needs to be carefully checked.
Filter Capacitors
: This module's input and output capacitors consist of 8 solid-state through-hole capacitors and 16 tantalum capacitors.
These capacitors also determine the module's ripple performance (and price); pay attention to the packaging and voltage rating when selecting them.
Ripple performance – Further
verification needed
. Verified; stable operation in 8-bay configuration.

ESP32 C3 keeps displaying pop-up messages (onboard antenna)

Make your Apple device bombarded with pop-ups.

Uploading via VS Code
requires the latest version. Please visit:
https://oshwhub.com/qusenberg/feng-kuang-dan-chuang-pro
. For maximum power, add the following source code below `BLEDevice:init("Airpords69)"`: `
esp_ble_tx_power_set(ESP_BLE_PWR_TYPE_AD V, ESP_PWR_LVL_P21);
esp_ble_tx_power_set(ESP_BLE_PWR_TYPE_SC AN, ESP_PWR_LVL_P21);
esp_ble_tx_power_set(ESP_BLE_PWR_TYPE_DEF AULT, ESP_PWR_LVL_P21);
` Effective distance ≥ 3m.
Materials:
1) Thickness, width, and length 70, 20, 25mm; Battery - 300mA (antenna version is 150mA);
2) Copper pillars M2*8 (4 pieces), M2 screws (8 pieces).
3) 3M double-sided tape for fixing the battery
 
                                                                                                                                    
V1.0 (October 18, 2023):
1) Simplified the size of the ESP32 development board, and added a battery management module later for easy portability without external power supply;
V1.1 (October 23, 2023) :
1) Changed ESP32 S3 to ESP C3 to reduce cost;
2) Added a power switch (forgot to mention, oops!);
V1.2 (October 24, 2023): 1
) Circuit fine-tuning;
V1.3 (November 4, 2023):
1) Added a step-down voltage regulator chip to solve the problem of program download failure without battery installation (useless); 2
) Added battery pads;
3) Circuit adjustments;
