Product details
Overview
TDGL026 from Microchip Technology is a Pmod expansion shield designed to interface Digilent peripheral modules (Pmods) with chipKIT uC32 (TDGL017) and legacy chipKIT Uno32 microcontroller development boards. It provides five 2×6 Pmod connectors, one 6-pin SPI header, and one I2C daisy-chain connector for scalable peripheral integration in embedded prototyping.
For engineers reviewing the TDGL026 datasheet, TDGL026 pinout, TDGL026 application, or TDGL026 equivalent, this shield enables rapid hardware extension using standardized Digilent Pmod interfaces while maintaining compatibility with existing chipKIT firmware and Arduino-style IDE toolchains.
Technical Context
The TDGL026 operates as a passive interconnect layer-no active logic, voltage translation, or power regulation is integrated. All Pmod connectors route native I/O signals directly from the base board's MCU GPIO, SPI, and I2C peripherals without buffering or level-shifting.
Signal integrity is maintained via 100-mil pitch headers and routed traces matching Digilent's Pmod specification v1.2. The shield supports 3.3 V logic only and does not include pull-up resistors on the I2C bus-external termination is required per connected Pmod.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pmod Connectors | Five 2×6-pin headers compliant with Digilent Pmod standard v1.2 |
| SPI Header | One 6-pin unbuffered SPI interface routed to MCU SPI peripheral pins |
| I2C Connector | One 6-pin daisy-chain header for SDA/SCL with no on-board pull-ups |
| Logic Level | 3.3 V only-no level-shifting circuitry; requires 3.3 V base board |
| Mechanical Fit | Designed for chipKIT uC32 (TDGL017); compatible with discontinued Uno32 form factor |

FAQ
Does TDGL026 require external power or voltage regulation?
No. TDGL026 is a passive shield with no onboard regulators, DC-DC converters, or power management circuitry. It draws all power-including 3.3 V and ground-from the host chipKIT uC32 (TDGL017) board via the standard 2×15 header footprint. Users must ensure the base board supplies sufficient current for connected Pmods.
Is TDGL026 compatible with PIC32MX-based chipKIT boards other than uC32 and Uno32?
TDGL026 is mechanically and electrically validated only for chipKIT uC32 (TDGL017) and the discontinued Uno32. While other PIC32MX-based boards sharing identical pinout and 2×15 header layout may physically fit, signal mapping, I2C/SPI pin assignments, and reset behavior are not guaranteed-TDGL026 functionality depends on exact base board signal routing.
What Pmod standards does TDGL026 support?
TDGL026 implements Digilent's Pmod standard v1.2 across all five 2×6 connectors. Each supports up to six bidirectional digital I/O lines, with dedicated SPI and I2C headers routed to corresponding MCU peripherals. No Pmod JEDEC-compliant analog or high-speed variants (e.g., Pmod HB5, Pmod VGA) are supported due to lack of specialized signal conditioning.
Does TDGL026 include I2C pull-up resistors?
No. TDGL026 provides only the physical 6-pin I2C daisy-chain connector with direct SDA/SCL routing to the base board's MCU pins. Pull-up resistors must be added externally-either on the Pmod itself or on the base board-as specified by I2C bus capacitance and speed requirements. TDGL026 does not integrate any passive components for I2C termination.
Can TDGL026 be used with non-chipKIT Arduino-compatible boards?
TDGL026 is not designed for generic Arduino boards. Its 2×15 header footprint, pin mapping, and signal assignments match only chipKIT uC32 (TDGL017) and Uno32. Using it with other platforms risks incorrect signal routing, voltage mismatch, or mechanical interference-TDGL026 requires precise alignment with chipKIT-specific GPIO, SPI, and I2C pin locations.
